Your menuItem element doesn't have an ancestor called pageID so
ancestor-or-self::pageID will select nothing.
I'm not really sure what you want but you seem to need descendants rather
than ancestors.

Subject: [xsl] What's wrong with my ancestor syntax?
I'm trying to use ancestor-or-self.
Here's a sample of the XML:
<menuItems>
<menuItem>
<pageID>938</pageID>
<browserTitle>Home Page</browserTitle>
<lastUpdate>2006/06/12</lastUpdate>
<menuItem>
<pageID>998</pageID>
<browserTitle>District Administration</browserTitle>
<lastUpdate>2006/06/06</lastUpdate>
</menuItem>
</menuItem>
<menuItems>
This is the XML that forms our site menu. I want to create an
RSS feed that lists the most recent 10 pages that have been
changed under a certain node of the menu.
So, for this example, I want to pass in the page ID of '938'
and return both '938' and any child page underneath it.
Here's the XSL:
<xsl:param name="pageID">1</xsl:param>
<xsl:template match="/">
<xsl:for-each
select="*/menuItem[ancestor-or-self::pageID = $pageID]">
<xsl:sort select="substring(@lastUpdate,1,4)"
order="descending" /> <!-- year -->
<xsl:sort select="substring(@lastUpdate,6,2)"
order="descending" /> <!-- month -->
<xsl:sort select="substring(@lastUpdate,9,2)"
order="descending" /> <!-- day -->
<xsl:call-template name="createItem" />
</xsl:for-each>
</xsl:template>
<xsl:template name="createItem">
lastUpdate: <xsl:value-of select="lastUpdate"/>
browserTitle: <xsl:value-of select="browserTitle"/>
pageID: <xsl:value-of select="pageID"/> </xsl:template>
Originally, I had 'descendant-or-self' by mistake which
obviously gave me the exact opposite of what I wanted and
returned the specific node and all PARENT pages that matched.
So I changed to ancestor-or-self and now it doesn't appear to
match anything. I'm not sure why. Is my logic a bit off?
