This page describes the XHTML-based format that Confluence uses to store the content of pages, page templates, blueprints, blog posts and comments. This information is intended for advanced users who need to interpret and edit the underlying markup of a Confluence page. 

We refer to the Confluence storage format as 'XHTML-based'. To be correct, we should call it XML, because the Confluence storage format does not comply with the XHTML definition. In particular, Confluence includes custom elements for macros and more. We're using the term 'XHTML-based' to indicate that there is a large proportion of HTML in the storage format.

</ac:link>

For rich content like images, you need to use ac:link-body to wrap the contents.


A note about link bodies

All links received from the editor will be stored as plain text by default, unless they are detected to contain the limited set of mark up that we allow in link bodies. Here are some examples of markup we support in link bodies.

An example of different link bodies
<ac:link>
  <!-- Any resource identifier --> 
  <ri:page ri:content-title="Home" ri:space-key="SANDBOX" /> 
  <ac:link-body>Some <strong>Rich</strong> Text</ac:link-body>
</ac:link>
<ac:link>
  <ri:page ri:content-title="Plugin developer tutorial stuff" ri:space-key="TECHWRITING" />
  <ac:plain-text-link-body><![CDATA[A plain <text> link body]]></ac:plain-text-link-body>
</ac:link>
<ac:link>
  <ri:page ri:content-title="Plugin developer tutorial stuff" ri:space-key="TECHWRITING" />
  <!-- A link body isn't necessary. Auto-generated from the resource identifier for display. --> 
</ac:link>


The markup tags permitted within the <ac:link-body> are <b>, <strong>, <em>, <i>, <code>, <tt>, <sub>, <sup>, <br> and <span>.

Images

<ri:url ri:value="http://confluence.atlassian.com/

Supported image attributes (some of these attributes mirror the equivalent HTML 4 IMG element): 

NameDescription
ac:alignimage alignment
ac:borderSet to "true" to set a border
ac:classcss class attribute.
ac:titleimage tool tip.
ac:stylecss style

Page layouts

Confluence supports page layouts directly, as an alternative to macro-based layouts (using, for example, the section and column macros). This section documents the storage format XML created when these layouts are used in a page.

Element nameIn Confluence 5.2 and laterAttributes
ac:layout

Indicates that the page has a layout. It should be the top level element in the page.

None
ac:layout-section

Represents a row in the layout. It must be directly within the ac:layout tag. The type of the section indicates the appropriate number of cells and their relative widths.


ac:type
ac:layout-cellRepresents a column in a layout. It must be directly within the ac:layout-section tag. There should be an appropriate number of cells within the layout-section to match the ac:type.None

The recognized values of ac:type for ac:layout-section are:

ac:type

Expected number of cells

Description

single

1One cell occupies the entire section.
two_equal 2Two cells of equal width.
two_left_sidebar 2A narrow (~30%) cell followed by a wide cell.
two_right_sidebar 2A wide cell followed by a narrow (~30%) cell.
three_equal 3Three cells of equal width.
three_with_sidebars 3A narrow (~20%) cell at each end with a wide cell in the middle.

The following example shows one of the more complicated layouts from the old format built in the new. The word {content} indicates where further XHTML or Confluence storage format block content would be entered, such as <p> or <table> tags.

<ac:layout>
  <ac:layout-section ac:type="single">
     <ac:layout-cell>
        {content}
     </ac:layout-cell>
  </ac:layout-section>
 <ac:layout-section ac:type="three_with_sidebars">
     <ac:layout-cell>
       {content}
     </ac:layout-cell>
     <ac:layout-cell>
       {content}
     </ac:layout-cell>
     <ac:layout-cell>
       {content}
     </ac:layout-cell>
  </ac:layout-section>
  <ac:layout-section ac:type="single">
     <ac:layout-cell>
        {content}
     </ac:layout-cell>
  </ac:layout-section>
</ac:layout>

Resource identifiers

Resource identifiers are used to describe "links" or "references" to resources in the storage format. Examples of resources include pages, blog posts, comments, shortcuts, images and so forth. 

Resource

Resource identifier format
Page
<ri:page ri:space-key="FOO" ri:content-title="Test Page"/>

Notes:

  • ri:space-key: (optional) denotes the space key. This can be omitted to create a relative reference.
  • ri:content-title: (required) denotes the title of the page.
Blog Post
<ri:blog-post ri:space-key="FOO" ri:content-title="First Post" ri:posting-day="2012/01/30" />

Notes:

  • ri:space-key: (optional) denotes the space key. This can be omitted to create a relative reference.
  • ri:content-title: (required) denotes the title of the page.
  • ri:posting-day: (required) denotes the posting day. The format is YYYY/MM/DD.
Attachment
<ri:attachment ri:filename>
	... resource identifier for the container of the attachment ...
</ri:attachment>

Notes:

  • ri:filename: (required) denotes the name of the attachment.
  • the body of the ri:attachment element should be a resource identifier denoting the container of the attachment. This can be omitted to create a relative attachment reference (similar to [foo.png] in wiki markup).

Examples:

Relative Attachment Reference
<ri:attachment ri:filename="happy.gif" />
Absolute Attachment Reference
<ri:attachment ri:filename="happy.gif">
	<ri:page ri:space-key="TST" ri:content-title="Test Page"/>
</ri:attachment>
URL
<ri:url ri:value="http://example.org/sample.gif"/>

Notes:

  • ri:value: (required) denotes the actual URL value.
Shortcut
<ri:shortcut ri:key="jira" ri:parameter="ABC-123">

Notes:

  • ri:key: (required) represents the key of the Confluence shortcut.
  • ri:parameter: (required) represents the parameter to pass into the Confluence shortcut.
  • The example above is equivalent to [ABC-123@jira] in wiki markup.
User
<ri:user ri:userkey="2c9680f7405147ee0140514c26120003"/>

Notes:

  • ri:userkey: (required) denotes the unique identifier of the user.
Space
<ri:space ri:space-key="TST"/>

Notes:

  • ri:space-key: (required) denotes the key of the space.
Content Entity
<ri:content-entity ri:content-id="123"/>

Notes:

  • ri:content-id: (required) denotes the id of the content.

Template variables

This screenshot shows a simple template:

The template contains the following variables:

Variable nameTypeValues
$MyTextSingle-line text
$MyMultiMulti-line textSize: 5 x 100
$MyListListList items: Apples,Pears,Peaches

The XML export produces the following code for the template:

<at:declarations>
  <at:string at:name="MyText" />
  <at:textarea at:columns="100" at:name="MyMulti" at:rows="5" />
  <at:list at:name="MyList">
    <at:option at:value="Apples" />
    <at:option at:value="Pears" />
    <at:option at:value="Peaches" />
  </at:list>
</at:declarations>


<p>This is Sarah's template</p>

<p>A single-line text variable:&nbsp;<at:var at:name="MyText" /></p>

<p>A multi-line text variable:&nbsp;<at:var at:name="MyMulti" /></p>

<p>A selection list:&nbsp;<at:var at:name="MyList" /></p>

<p>End of page.</p>

Instructional Text

Instructional text allows you to include information on how to fill out a template for an end-user (the person using creating a page from the template). Instructional text will:

  • automatically clear all instructional text as the user types in a specific text block, and
  • automatically trigger a @mention prompt for user selection (for 'mention' type instructional text).

Screenshot: Example of instructional text.

<ul>
    
<li><ac:placeholder>This is an example of instruction text that will get replaced when a user selects the text and begins typing.</ac:placeholder></li>
</ul>
<ac:task-list>
    <ac:task>
        <ac:task-status>incomplete</ac:task-status>
        <ac:task-body><ac:placeholder ac:type="mention">@mention example. This placeholder will automatically search for a user to mention in the page when the user begins typing.</ac:placeholder></ac:task-body>
    </ac:task>
</ac:task-list>
