This document describes the XML data structure of Docutils documents: the relationships and semantics of elements and attributes. The Docutils document structure is formally defined by the Docutils Generic DTD XML document type definition, docutils.dtd, which is the definitive source for details of element structural relationships.

This document does not discuss implementation details. Those can be found in internal documentation (docstrings) for the docutils.nodes module, where the document tree data structure is implemented in a class library.

The reader is assumed to have some familiarity with XML or SGML, and an understanding of the data structure meaning of "tree". For a list of introductory articles, see Introducing the Extensible Markup Language (XML).

The reStructuredText markup is used for illustrative examples throughout this document. For a gentle introduction, see A ReStructuredText Primer. For complete technical details, see the reStructuredText Markup Specification.

Element Hierarchy

Below is a simplified diagram of the hierarchy of elements in the Docutils document tree structure. An element may contain any other elements immediately below it in the diagram. Notes are written in square brackets. Element types in parentheses indicate recursive or one-to-many relationships; sections may contain (sub)sections, tables contain further body elements, etc.

+--------------------------------------------------------------------+
| document  [may begin with a title, subtitle, decoration, docinfo]  |
|                             +--------------------------------------+
|                             | sections  [each begins with a title] |
+-----------------------------+-------------------------+------------+
| [body elements:]                                      | (sections) |
|         | - literal | - lists  |       | - hyperlink  +------------+
|         |   blocks  | - tables |       |   targets    |

| (inline +-----------+------------------+--------------+
| markup) |
+---------+

The Docutils document model uses a simple, recursive model for section structure. A document node may contain body elements and section elements. Sections in turn may contain body elements and sections. The level (depth) of a section element is determined from its physical nesting level; unlike other document models (<h1> in HTML, <sect1> in DocBook, <div1> in XMLSpec) the level is not incorporated into the element name.

The Docutils document model uses strict element content models. Every element has a unique structure and semantics, but elements may be classified into general categories (below). Only elements which are meant to directly contain text data have a mixed content model, where text data and inline elements may be intermixed. This is unlike the much looser HTML document model, where paragraphs and text data may occur at the same level.

Structural Elements

Structural elements may only contain child elements; they do not directly contain text data. Structural elements may contain body elements or further structural elements. Structural elements can only be child elements of other structural elements.

Category members: document, section, topic, sidebar

Structural Subelements

Structural subelements are child elements of structural elements. Simple structuctural subelements (title, subtitle) contain text data; the others are compound and do not directly contain text data.

Category members: title, subtitle, decoration, docinfo, transition

Bibliographic Elements

The docinfo element is an optional child of document. It groups bibliographic elements together. All bibliographic elements except authors and field contain text data. authors contains further bibliographic elements (most notably author). field contains field_name and field_body body subelements.

Category members: address, author, authors, contact, copyright, date, field, organization, revision, status, version

Decorative Elements

The decoration element is also an optional child of document. It groups together elements used to generate page headers and footers.

Category members: footer, header

Body Elements

Body elements are contained within structural elements and compound body elements. There are two subcategories of body elements: simple and compound.

Category members: admonition, attention, block_quote, bullet_list, caution, citation, comment, compound, container, danger, definition_list, doctest_block, enumerated_list, error, field_list, figure, footnote, hint, image, important, line_block, literal_block, note, option_list, paragraph, pending, raw, rubric, substitution_definition, system_message, table, target, tip, warning

Simple Body Elements

Simple body elements are empty or directly contain text data. Those that contain text data may also contain inline elements. Such elements therefore have a "mixed content model".

Category members: comment, doctest_block, image, literal_block, math_block, paragraph, pending, raw, rubric, substitution_definition, target

Compound Body Elements

Compound body elements contain local substructure (body subelements) and further body elements. They do not directly contain text data.

Category members: admonition, attention, block_quote, bullet_list, caution, citation, compound, container, danger, definition_list, enumerated_list, error, field_list, figure, footnote, hint, important, line_block, note, option_list, system_message, table, tip, warning

Body Subelements

Compound body elements contain specific subelements (e.g. bullet_list contains list_item). Subelements may themselves be compound elements (containing further child elements, like field) or simple data elements (containing text data, like field_name). These subelements always occur within specific parent elements, never at the body element level (beside paragraphs, etc.).

Category members (simple): attribution, caption, classifier, colspec, field_name, label, line, option_argument, option_string, term

Category members (compound): definition, definition_list_item, description, entry, field, field_body, legend, list_item, option, option_group, option_list_item, row, tbody, tgroup, thead

Inline Elements

Inline elements directly contain text data, and may also contain further inline elements. Inline elements are contained within simple body elements. Most inline elements have a "mixed content model".

Category members: abbreviation, acronym, citation_reference, emphasis, footnote_reference, generated, image, inline, literal, math, problematic, reference, strong, subscript, substitution_reference, superscript, target, title_reference, raw

Element Reference

Each element in the DTD (document type definition) is described in its own section below. Each section contains an introduction plus the following subsections:


Many of the element reference sections below are marked "to be completed". Please help complete this document by contributing to its writing.

abbreviation

The abbreviation element is an inline element used to represent an abbreviation being used in the document. An example of an abbreviation is 'St' being used instead of 'Street'.

Details

Category:Inline Elements
Parents:All elements employing the %inline.elements; parameter entities in their content models may contain abbreviation.
Children:abbreviation elements may contain text data plus inline elements.
Analogues:abbreviation is analogous to the HTML "abbr" element.

Content Model

%text.model;
Attributes:The abbreviation element contains only the common attributes: ids, names, dupnames, source, and classes.

Examples

The abbreviation element is not exposed in default restructured text. It can only be accessed through custom roles.

Pseudo-XML example from a custom :abbr: role:

<paragraph>
    <abbreviation explanation="Street">
        St
    is a common abbreviation for "street".

address

The address element holds the surface mailing address information for the author (individual or group) of the document, or a third-party contact address. Its structure is identical to that of the literal_block element: whitespace is significant, especially newlines.

Details

Category:

Bibliographic Elements

Parents:

The following elements may contain address: docinfo, authors

Children:

address elements contain text data plus inline elements.

Analogues:

address is analogous to the DocBook "address" element.

Processing:

As with the literal_block element, newlines and other whitespace is significant and must be preserved. However, a monospaced typeface need not be used.

See also docinfo.

Content Model

%text.model;
Attributes:The address element contains the common attributes (ids, names, dupnames, source, and classes), plus xml:space.
Parameter Entities:The %bibliographic.elements; parameter entity directly includes address.

                J. Random Hacker
            <author>
                Jane Doe

In reStructuredText, multiple author's names are separated with semicolons (";") or commas (","); semicolons take precedence. There is currently no way to represent the author's organization, address, or contact in a reStructuredText "Authors" field.

See docinfo for a more complete example, including processing context.

block_quote

The block_quote element is used for quotations set off from the main text (standalone).

Pseudo-XML fragment from simple parsing:

<paragraph>
    As a great paleontologist once said,
<block_quote>
    <paragraph>
        This theory, that is mine, is mine.
    <attribution>
        Anne Elk (Miss)

bullet_list

The bullet_list element contains list_item elements which are uniformly marked with bullets. Bullets are typically simple dingbats (symbols) such as circles and squares.

Details

Category:Compound Body Elements
Parents:All elements employing the %body.elements; or %structure.model; parameter entities in their content models may contain bullet_list.
Children:bullet_list elements contain one or more list_item elements.
Analogues:bullet_list is analogous to the HTML "ul" element and to the DocBook "itemizedlist" element. HTML's "ul" is short for "unordered list", which we consider to be a misnomer. "Unordered" implies that the list items may be randomly rearranged without affecting the meaning of the list. Bullet lists are often ordered; the ordering is simply left implicit.
Processing:Each list item should begin a new vertical block, prefaced by a bullet/dingbat.

Content Model

(list_item +)
Attributes:

The bullet_list element contains the common attributes (ids, names, dupnames, source, and classes), plus bullet.

bullet is used to record the style of bullet from the input data. In documents processed from reStructuredText, it contains one of "-", "+", or "*". It may be ignored in processing.

Parameter Entities:

The %body.elements; parameter entity directly includes bullet_list. The %structure.model; parameter entity indirectly includes bullet_list.

Examples

reStructuredText source:

- Item 1, paragraph 1.

  Item 1, paragraph 2.

- Item 2.

Pseudo-XML fragment from simple parsing:

<bullet_list bullet="-">
    <list_item>
        <paragraph>
            Item 1, paragraph 1.
        <paragraph>
            Item 1, paragraph 2.
    <list_item>
        <paragraph>
            Item 2.

See list_item for another example.

caution

The caution element is an admonition, a distinctive and self-contained notice. Also see the other admonition elements Docutils offers (in alphabetical order): attention, danger, error, hint, important, note, tip, warning, and the generic admonition.

Details

Category:Compound Body Elements
Parents:All elements employing the %body.elements; or %structure.model; parameter entities in their content models may contain caution.
Children:caution elements contain one or more body elements.
Analogues:caution is analogous to the DocBook "caution" element.
Processing:Rendered distinctly (inset and/or in a box, etc.), with the generated title "Caution" (or similar).

Content Model

(%body.elements;)+
Attributes:The caution element contains only the common attributes: ids, names, dupnames, source, and classes.
Parameter Entities:The %body.elements; parameter entity directly includes caution. The %structure.model; parameter entity indirectly includes caution.

docinfo

The docinfo element is a container for document bibliographic data, or meta-data (data about the document). It corresponds to the front matter of a book, such as the title page and copyright page.

Details

Category:

Structural Subelements

Parents:

Only the document element contains docinfo.

Children:

docinfo elements contain bibliographic elements.

Analogues:

docinfo is analogous to DocBook "info" elements ("bookinfo" etc.). There are no directly analogous HTML elements; the "meta" element carries some of the same information, albeit invisibly.

Processing:

The docinfo element may be rendered as a two-column table or in other styles. It may even be invisible or omitted from the processed output. Meta-data may be extracted from docinfo children; for example, HTML <meta> tags may be constructed.

When Docutils transforms a reStructuredText field_list into a docinfo element (see the examples below), RCS/CVS keywords are normally stripped from simple (one paragraph) field bodies. For complete details, please see RCS Keywords in the reStructuredText Markup Specification.

Content Model

(%bibliographic.elements;)+
Attributes:The docinfo element contains only the common attributes: ids, names, dupnames, source, and classes.

Examples

Docinfo is represented in reStructuredText by a field_list in a bibliographic context: the first non-comment element of a document, after any document title/subtitle. The field list is transformed into a docinfo element and its children by a transform. Source:

doctest_block

The doctest_block element is a Python-specific variant of literal_block. It is a block of text where line breaks and whitespace are significant and must be preserved. doctest_block elements are used for interactive Python interpreter sessions, which are distinguished by their input prompt: >>>. They are meant to illustrate usage by example, and provide an elegant and powerful testing environment via the doctest module in the Python standard library.

Details

Category:Simple Body Elements
Parents:All elements employing the %body.elements; or %structure.model; parameter entities in their content models may contain doctest_block.
Children:doctest_block elements may contain text data plus inline elements.
Analogues:doctest_block is analogous to the HTML "pre" element and to the DocBook "programlisting" and "screen" elements.
Processing:As with literal_block, doctest_block elements are typically rendered in a monospaced typeface. It is crucial that all whitespace and line breaks are preserved in the rendered form.

Content Model

%text.model;
Attributes:The doctest_block element contains the common attributes (ids, names, dupnames, source, and classes), plus xml:space.
Parameter Entities:The %body.elements; parameter entity directly includes doctest_block. The %structure.model; parameter entity indirectly includes doctest_block.

Examples

reStructuredText source:

This is an ordinary paragraph.

>>> print 'this is a Doctest block'
this is a Doctest block

Pseudo-XML fragment from simple parsing:

<paragraph>
    This is an ordinary paragraph.
<doctest_block xml:space="preserve">
    >>> print 'this is a Doctest block'
    this is a Doctest block

document

The document element is the root (topmost) element of the Docutils document tree. document is the direct or indirect ancestor of every other element in the tree. It encloses the entire document tree. It is the starting point for a document.

Details

Category:Structural Elements
Parents:The document element has no parents.
Children:document elements may contain structural subelements, structural elements, and body elements.
Analogues:document is analogous to the HTML "html" element and to several DocBook elements such as "book".

Content Model

( (title, subtitle?)?,
  decoration?,
  (docinfo, transition?)?,
  %structure.model; )

Depending on the source of the data and the stage of processing, the "document" may not initially contain a "title". A document title is not directly representable in reStructuredText. Instead, a lone top-level section may have its title promoted to become the document title, and similarly for a lone second-level (sub)section's title to become the document subtitle.

The contents of "decoration" may be specified in a document, constructed programmatically, or both. The "docinfo" may be transformed from an initial field_list.

See the %structure.model; parameter entity for details of the body of a document.

Attributes:The document element contains the common attributes (ids, names, dupnames, source, and classes), plus an optional title attribute which stores the document title metadata.

Examples

reStructuredText source:

A Title
=======

A paragraph.

Complete pseudo-XML result from simple parsing:

<document>
    <section ids="a-title" names="a title">
        <title>
            A Title
        <paragraph>
            A paragraph.

After applying transforms, the section title is promoted to become the document title:

<document ids="a-title" names="a title">
    <title>
        A Title
    <paragraph>
        A paragraph.

enumerated_list

The enumerated_list element contains list_item elements which are uniformly marked with enumerator labels.

Details

Category:Compound Body Elements
Parents:All elements employing the %body.elements; or %structure.model; parameter entities in their content models may contain enumerated_list.
Children:enumerated_list elements contain one or more list_item elements.
Analogues:enumerated_list is analogous to the HTML "ol" element and to the DocBook "orderedlist" element.
Processing:Each list item should begin a new vertical block, prefaced by a enumeration marker (such as "1.").

Content Model

(list_item +)
Attributes:

The enumerated_list element contains the common attributes (ids, names, dupnames, source, and classes), plus enumtype, prefix, suffix, and start.

enumtype is used to record the intended enumeration sequence, one of "arabic" (1, 2, 3, ...), "loweralpha" (a, b, c, ..., z), "upperalpha" (A, B, C, ..., Z), "lowerroman" (i, ii, iii, iv, ..., mmmmcmxcix [4999]), or "upperroman" (I, II, III, IV, ..., MMMMCMXCIX [4999]).

prefix stores the formatting characters used before the enumerator. In documents originating from reStructuredText data, it will contain either "" (empty string) or "(" (left parenthesis). It may or may not affect processing.

suffix stores the formatting characters used after the enumerator. In documents originating from reStructuredText data, it will contain either "." (period) or ")" (right parenthesis). Depending on the capabilities of the output format, this attribute may or may not affect processing.

start contains the ordinal value of the first item in the list, in decimal. For lists beginning at value 1 ("1", "a", "A", "i", or "I"), this attribute may be omitted.

Parameter Entities:

The %body.elements; parameter entity directly includes enumerated_list. The %structure.model; parameter entity indirectly includes enumerated_list.

Examples

reStructuredText source:

1. Item 1.

   (A) Item A.
   (B) Item B.

transition

The transition element is commonly seen in novels and short fiction, as a gap spanning one or more lines, with or without a type ornament such as a row of asterisks. Transitions separate body elements and sections, dividing a section into untitled divisions. A transition may not begin or end a section [1] or document, nor may two transitions be immediately adjacent.

See Doctree Representation of Transitions in A Record of reStructuredText Syntax Alternatives.

[1]In reStructuredText markup, a transition may appear to fall at the end of a section immediately before another section. A transform recognizes this case and moves the transition so it separates the sections.

Attribute Reference

Common Attributes: Through the %basic.atts; parameter entity, all elements contain the following attributes: ids, names, dupnames, source, and classes.

Attribute types:

CDATA
Character data. CDATA attributes may contain arbitrary text.
ID
Like a NMTOKEN, but it must begin with a letter (a "name production"). Identical ID values must not appear more than once in a document; i.e., ID values must uniquely identify their elements.
IDREF
A reference to an ID value (a name production) of another element.
IDREFS
One or more space-separated ID references (name productions).
NMTOKEN
A "name token". One or more of letters, digits, ".", "-", and "_".
NMTOKENS
One or more space-separated NMTOKEN names.
%yesorno;
No if zero ("0"), yes if any other value. This is a parameter entity which resolves to a NMTOKEN attribute type.
%number;
This emphasizes that the attribute value must be a number. This is a parameter entity which resolves to a NMTOKEN attribute type.
enumeration
The attribute value may be one of a specified list of values.

anonymous

Attribute type: %yesorno;. Default value: none (implies no).

The anonymous attribute is used for unnamed hyperlinks in the target and reference elements (via the %anonymous.att; parameter entity).

auto

Attribute type: CDATA. Default value: none.

The auto attribute is used to indicate automatically-numbered footnote, footnote_reference and title elements (via the %auto.att; parameter entity).

backrefs

Attribute type: IDREFS. Default value: none.

The backrefs attribute contains a space-separated list of ids references, used for backlinks from footnote, citation, and system_message elements (via the %backrefs.att; parameter entity).

bullet

Attribute type: CDATA. Default value: none.

The bullet attribute is used in the bullet_list element.

classes

Attribute type: NMTOKENS. Default value: none.

The classes attribute is a list containing zero or more names used to classify an element. The names are converted to conform to the regular expression [a-z](-?[a-z0-9]+)* (see the "class" directive description for details and rationale).

The purpose of the attribute is to indicate an "is-a" variant relationship, to allow an extensible way of defining sub-classes of existing elements. It can be used to carry context forward between a Docutils Reader and Writer, when a custom structure is reduced to a standardized document tree. One common use is in conjunction with stylesheets, to add selection criteria. It should not be used to carry formatting instructions or arbitrary content.

The classes attribute's contents should be ignorable. Writers that are not familiar with the variant expressed should be able to ignore the attribute.

classes is one of the common attributes, shared by all Docutils elements.

delimiter

Attribute type: CDATA. Default value: none.

The delimiter attribute is used in the option_argument element.

dupnames

Attribute type: CDATA. Default value: none.

The dupnames attribute is a list containing the names of an element when there has been a naming conflict. The contents of the dupnames attribute would have been transferred from the names attribute. An element may have at most one of the names or dupnames attributes, but not both. dupnames is one of the common attributes, shared by all Docutils elements.

enumtype

Attribute type: enumeration, one of "arabic", "loweralpha", "upperalpha", "lowerroman", or "upperroman". Default value: none.

The enumtype attribute is used in the enumerated_list element.

ids

Attribute type: NMTOKENS. Default value: none.

The ids attribute is a list containing one or more unique identifier keys. ids is one of the common attributes, shared by all Docutils elements.

names

Attribute type: CDATA. Default value: none.

The names attribute is a list containing the names of an element, typically originating from the element's title or content. Each name in names must be unique; if there are name conflicts (two or more elements want to the same name), the contents will be transferred to the dupnames attribute on the duplicate elements. An element may have at most one of the names or dupnames attributes, but not both. names is one of the common attributes, shared by all Docutils elements.

prefix

Attribute type: CDATA. Default value: none.

The prefix attribute is used in the enumerated_list element.

refid

Attribute type: IDREF. Default value: none.

The refid attribute contains references to ids attributes in other elements. It is used by the target, reference, footnote_reference, citation_reference, title and problematic elements (via the %refid.att; and %reference.atts; parameter entities).

refname

Attribute type: NMTOKENS. Default value: none.

The refname attribute contains an internal reference to the names attribute of another element. On a target element, refname indicates an indirect target which may resolve to either an internal or external reference. refname is used by the target, reference, footnote_reference, citation_reference, and substitution_reference elements (via the %refname.att; and %reference.atts; parameter entities).

refuri

Attribute type: CDATA. Default value: none.

The refuri attribute contains an external reference to a URI/URL. It is used by the target, reference, footnote_reference, and citation_reference elements (via the %reference.atts; parameter entity).

source

Attribute type: CDATA. Default value: none.

The source attribute is used to store the path or URL to the source text that was used to produce the document tree. It is one of the common attributes, shared by all Docutils elements.

start

Attribute type: %number;. Default value: none.

The start attribute is used in the enumerated_list element.

suffix

Attribute type: CDATA. Default value: none.

The suffix attribute is used in the enumerated_list element.

xml:space

Attribute type: one of "default" or "preserve". Default value: "preserve" (fixed).

The xml:space attribute is a standard XML attribute for whitespace-preserving elements. It is used by the literal_block, line_block, doctest_block, comment, and raw elements (via the %fixedspace.att; parameter entity). It is a fixed attribute, meant to communicate to an XML parser that the element contains significant whitespace. The attribute value should not be set in a document instance.

title

Attribute type: CDATA. Default value: none.

The title attribute stores the title metadata of a document. This title is typically not part of the rendered document. It may for example be used in HTML's title element.

Parameter Entity Reference

Parameter entities are used to simplify the DTD (to share definitions and reduce duplication) and to allow the DTD to be customized by wrapper DTDs (external client DTDs that use or import the Docutils DTD). Parameter entities may be overridden by wrapper DTDs, replacing the definitions below with custom definitions.

refid   CDATA     #IMPLIED

The title and problematic elements directly employ the %refid.att; parameter entity in their attribute lists.

Via %reference.atts;, the %refid.att; parameter entity is indirectly employed in the attribute lists of the citation_reference, footnote_reference, reference, and target elements.

%refname.att;

The %refname.att; parameter entity contains the refname attribute, an internal reference to the names attribute of another element. On a target element, refname indicates an indirect target which may resolve to either an internal or external reference.

Entity definition:

refname  NMTOKENS  #IMPLIED

The substitution_reference element directly employs the %refname.att; parameter entity in its attribute list.

Via %reference.atts;, the %refname.att; parameter entity is indirectly employed in the attribute lists of the citation_reference, footnote_reference, reference, and target elements.

%refuri.att;

The %refuri.att; parameter entity contains the refuri attribute, an external reference to a URI/URL.

Entity definition:

refuri   CDATA     #IMPLIED

Via %reference.atts;, the %refuri.att; parameter entity is indirectly employed in the attribute lists of the citation_reference, footnote_reference, reference, and target elements.

%section.elements;

The %section.elements; parameter entity contains an OR-list of all section-equivalent elements. %section.elements; is itself contained within the %structure.model; parameter entity.

Entity definition:

section
%additional.section.elements;

The %additional.section.elements; parameter entity can be used by wrapper DTDs to extend %section.elements;.

Via %structure.model;, the %section.elements; parameter entity is indirectly employed in the content models of the document and section elements.

%structure.model;

The %structure.model; parameter entity encapsulates the hierarchical structure of a document and of its constituent parts. See the discussion of the element hierarchy above.

Entity definition:

( ( (%body.elements; | topic | sidebar)+, transition? )*,
  ( (%section.elements;), (transition?, (%section.elements;) )* )? )

Each document or section contains zero or more body elements, topics, and/or sidebars, optionally interspersed with single transitions, followed by zero or more sections (whose contents are recursively the same as this model) optionally interspersed with transitions.

The following restrictions are imposed by this model:

  • Transitions must be separated by other elements (body elements, sections, etc.). In other words, a transition may not be immediately adjacent to another transition.
  • A transition may not occur at the beginning of a document or section.

An additional restriction, which cannot be expressed in the language of DTDs, is imposed by software:

  • A transition may not occur at the end of a document or section.

The %structure.model; parameter entity is directly employed in the content models of the document and section elements.

%text.model;

The %text.model; parameter entity is used by many elements to represent text data mixed with inline elements.

Entity definition:

(#PCDATA | %inline.elements;)*

The %text.model; parameter entity is directly employed in the content models of the following elements: abbreviation, acronym, address, author, caption, classifier, contact, copyright, date, doctest_block, emphasis, field_name, generated, line_block, literal_block, organization, paragraph, problematic, raw, reference, revision, status, strong, substitution_definition, substitution_reference, subtitle, target, term, title, version
