Re: xpath help?

How do I get all possible sizes from the following XML
using only one xPath given the criteria of
ot[@id = 2 or @id  = 3] and ct[@id = 1]?

so, I'd want size id's = (2,4)??

T:\ftemp>type tomsic.xml
<hls>
  <hl>
    <ots>
       <ot id="2"/>
       <ot id="3"/>
    </ots>
    <cts>
       <ct id="1"/>
       <ct id="5"/>
    </cts>
    <sizes>
       <size id="2"/>
       <size id="4"/>
    </sizes>
  </hl>
  <hl>
    <ots>
       <ot id="2"/>
       <ot id="4"/>
    </ots>
    <cts>
       <ct id="2"/>
       <ct id="5"/>
    </cts>
    <sizes>
       <size id="3"/>
       <size id="8"/>
    </sizes>
  </hl>
</hls>

T:\ftemp>type tomsic.xsl
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:template match="/">
  <xsl:for-each
    select="//size[ancestor::hl[ots/ot[@id = 2 or @id  = 3] and
                                cts/ct[@id = 1] ] ]">
    <xsl:if test="position()!=1">,</xsl:if>
    <xsl:value-of select="@id"/>
  </xsl:for-each>
</xsl:template>

</xsl:stylesheet>
T:\ftemp>saxon tomsic.xml tomsic.xsl
2,4
T:\ftemp>
