RE: [xsl] Producing a Table of Contents

["M. David Peterson" <m.david@xxxxxxxxxx>]

Sure, using the document() function with nothing between the '' (single
quotes would normally have the name of the external xml file between
them) you can access elements within the current XSL document using the
correct namespace.  So, for example, using
"document('')/*/xsl:template//h1" as the match attribute and "toc" as
the mode attribute would locate all the h1 elements with the namespace
"xsl" and the local-name of "template" and put them into a Result Tree
Fragment that would then be processed by the matching template using
match="h1" and mode="toc"...

So this XSL...

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
  <xsl:strip-space elements="*"/>
  <xsl:output method="html"/>
  <xsl:template match="/">
    <xsl:text>Table of Contents:</xsl:text>
    <br/>
    <xsl:element name="ol">
      <xsl:apply-templates select="document('')/*/xsl:template//h1"
mode="toc"/>
    </xsl:element>
    <br/>
    <h1>this is heading 1</h1>
    <p>this is paragraph one <b>with bold text <i>with bold and
italicized text</i>
      </b>
      <i> with italicized text</i>
    </p>
    <h1>this is heading 2</h1>
    <p>this is paragraph one <b>with bold text <i>with bold and
italicized text</i>
      </b>
      <i> with italicized text</i>
    </p>
    <h1>this is heading 3</h1>
    <p>this is paragraph one <b>with bold text <i>with bold and
italicized text</i>
      </b>
      <i> with italicized text</i>
    </p>
    <h1>this is heading 4</h1>
    <p>this is paragraph one <b>with bold text <i>with bold and
italicized text</i>
      </b>
      <i> with italicized text</i>
    </p>
  </xsl:template>
  
  <xsl:template match="h1 | p | b | i">
    <xsl:copy>
      <xsl:element name="name()">
        <xsl:apply-templates/>
      </xsl:element>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="h1" mode="toc">
    <xsl:element name="li">
      <xsl:value-of select="."/>
    </xsl:element>
  </xsl:template>

</xsl:stylesheet>

Would result in this HTML...

Table of Contents:<br>
<ol>
  <li>this is heading 1</li>
  <li>this is heading 2</li>
  <li>this is heading 3</li>
  <li>this is heading 4</li>
</ol>
<br>
<h1>this is heading 1</h1>
<p>this is paragraph one <b>with bold text <i>with bold and italicized
text</i></b><i> with italicized text</i>
</p>
<h1>this is heading 2</h1>
<p>this is paragraph one <b>with bold text <i>with bold and italicized
text</i></b><i> with italicized text</i>
</p>
<h1>this is heading 3</h1>
<p>this is paragraph one <b>with bold text <i>with bold and italicized
text</i></b><i> with italicized text</i>
</p>
<h1>this is heading 4</h1>
<p>this is paragraph one <b>with bold text <i>with bold and italicized
text</i></b><i> with italicized text</i>
</p>

Which, is the exact same output as before but using the current document
instead of the source XML as the source of its data.

Let me know if I can help answer any more of your questions :)

Best of luck!

Many thanks of for that.

Can the technique be applied in an XSLT document to search within itself

rather than a source XML file?
