Re: parsing a complex xml tree into simple trees (a challenging problem

I think that would be quite hard to do without any extension at all, the
following probably does what you want, and uses the node-set extension
which most processors support (apart from mozilla). I used the exslt
namespace as I think xalan supports that, although I tested this with
saxon. This would probably be easier in xslt2.

<root> 
    <chops att1="something">1,2<X>XText1,XText2<Y>YT1,YT2</Y></X></chops>
</root>



<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
version="1.0"  
xmlns:exslt="http://exslt.org/common";
exclude-result-prefixes="exslt">


<xsl:template match="root">
<root>
  <xsl:apply-templates/>
</root>
</xsl:template>

<xsl:template match="chops">
 <xsl:param name="a" select=".//text()[contains(.,',')][1]"/>
 <xsl:param name="i" select="generate-id($a)"/>
 <xsl:choose>
   <xsl:when test="$a">
     <xsl:variable name="c">
     <xsl:text>&#10;</xsl:text>
     <chops>
    <xsl:copy-of select="@*"/>
       <xsl:apply-templates mode="c">
         <xsl:with-param name="i" select="$i"/>
         <xsl:with-param name="r" 
select="substring-before(concat($a,','),',')"/>
       </xsl:apply-templates>
     </chops>
      <xsl:if test="contains($a,',')">
      <xsl:apply-templates select=".">
        <xsl:with-param name="i" select="$i"/>
        <xsl:with-param name="a" select="substring-after($a,',')"/>
    </xsl:apply-templates>
      </xsl:if>
     </xsl:variable>
     <xsl:apply-templates select="exslt:node-set($c)/chops"/>
   </xsl:when>
