Where are the sample Xhtml and xml documents?

Hey list,
I want to create a nested list (ToC) from a XHTML source, which
contains @class attributes on elements.
A separate document, styles.xml, contains information about styles and
which outline level they belong to. @style:name matches @class in
XHTML.
The tricky part is, that not all styles are necessarily used in XHTML.
And if they are, the outline hierarchy is not necessarily maintained
-- for example, only styles with level 1, 3 and 5 can be used.
How would you traverse such a structure? My approach is to do it
recursively, by finding all styles for the current level, and all
elements of these styles (simplified):
<xsl:template match="h:*">
<xsl:param name="level" select="1"/>
<xsl:variable name="level-classes" select="key('style-by-level',
$level, $styles-doc)//@style:name
<xsl:variable name="level-elements" select="key('element-by-class',
$level-classes)"/>
<li>
<xsl:value-of select="."/>
<ol>
<xsl:apply-templates="$level-elements">
<xsl:with-param name="level" select="$level + 1"/>
</xsl:apply-templates>
</ol>
</li>
</xsl:template>
But this gives problems since levels are not necessarily consecutive.
The first level can be 2, for example.
I also tried iterating only through actually used levels like (1, 3,
5), but it's not a full solution either, because the level hierarchy
can differ in each branch.
Help appreciated.
