I'm grouping bulleted items and embedding them as a second list of bulleted items inside some list elements. I can get the items to group, but my recursion template is selecting everything from my current position in the doc to the end. I need to set an ending point for my nested lists.

My output looks like this:

<ul>
    <li>First Bullet:<ul>
         <li>Sub-bullet 1: info for sub-bullet
                                            1</li>
         <li>Sub-bullet 2: info for sub-bullet
                                            2</li>
         <li>Sub-bullet 3: info for sub-bullet
                                            3</li>
         <li>Sub-bullet 4: info for sub-bullet
                                                4</li>
         <li>Sub-bullet 5: info for sub-bullet
                                            5</li>
         <li>Sub-bullet 6: info for sub-bullet
                                            6</li>
        </ul>
    </li>

    <li>Second Bullet:<ul>
         <li>Sub-bullet 5: info for sub-bullet
                                            5</li>
         <li>Sub-bullet 6: info for sub-bullet
                                            6</li>
        </ul>
    </li>
</ul>

But it SHOULD look like this (without Sub-bullets 5 and 6 under the first li):

<ul>
    <li>First Bullet:<ul>
         <li>Sub-bullet 1: info for sub-bullet
                                            1</li>
         <li>Sub-bullet 2: info for sub-bullet
                                            2</li>
         <li>Sub-bullet 3: info for sub-bullet
                                            3</li>
         <li>Sub-bullet 4: info for sub-bullet
                                                4</li>
        </ul>
    </li>

    <li>Second Bullet:<ul>
         <li>Sub-bullet 5: info for sub-bullet
                                            5</li>
         <li>Sub-bullet 6: info for sub-bullet
                                            6</li>
        </ul>
    </li>
</ul>

I'm not sure how to properly group the sub-bullets in XSLT to get them in the correct position.

Any suggestions on how to accomplish this in 2.0? I've attempted to create some count variables, but haven't had any luck yet on establishing an endpoint outside of the current-group context. I know there must be an obvious (and more elegant) way to get this done.

There is a short, simple and easy solution that doesn't require XSLT 2.0 at all:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:text="urn:oasis:names:tc:opendocument:xmlns:text:1.0"
 exclude-result-prefixes="text"
 >
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:template match="text:list">
  <ul><xsl:apply-templates/></ul>
 </xsl:template>

 <xsl:template match="text:list-item[not(text:list)]">
  <li><xsl:apply-templates/></li>
 </xsl:template>

 <xsl:template match=
  "text()[not(ancestor::text:list-item)]"/>
</xsl:stylesheet>

When this transformation is applied on the provided XML document:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<office:document-content xmlns:dom="http://www.w3.org/2001/xml-events"

            </draw:page>
        </office:presentation>
    </office:body>
</office:document-content>

the wanted, correct result is produced:

<ul>
   <li>First Bullet:</li>
</ul>
<ul>
   <ul>
      <li>Sub-bullet 1: info for sub-bullet                                             1</li>
   </ul>
</ul>
<ul>
   <ul>
      <li>Sub-bullet 2: info for sub-bullet                                             2</li>
   </ul>
</ul>
<ul>
   <ul>
      <li>Sub-bullet 3: info for sub-bullet                                             3</li>
   </ul>
</ul>
<ul>
   <ul>
      <li>Sub-bullet 4: info for sub-bullet                                                 4</li>
   </ul>
</ul>
<ul>
   <li>Second Bullet:</li>
</ul>
<ul>
   <ul>
      <li>Sub-bullet 5: info for sub-bullet                                             5</li>
   </ul>
</ul>
<ul>
   <ul>
      <li>Sub-bullet 6: info for sub-bullet                                             6</li>
   </ul>
</ul>

and the browser displays this as:

  • First Bullet:
    • Sub-bullet 1: info for sub-bullet 1
    • Sub-bullet 2: info for sub-bullet 2
    • Sub-bullet 3: info for sub-bullet 3
    • Sub-bullet 4: info for sub-bullet 4
  • Second Bullet:
    • Sub-bullet 5: info for sub-bullet 5
    • Sub-bullet 6: info for sub-bullet 6

You need a template that matches a text-list; this would output the <ul> tag.
