Re: Which XSL DTD to use and how do I find the depth o

Hello Uri,
 ad 2), I send you a hint, how find the level of nesting.
You must change it a little bit and extract the result
using string functions.

XML:
<a>
 <b>
  <c/>
 </b>
 <b>
  <c>
   <d/>
   <d>
    <e/>
   </d>
   <d/>
  </c>
 </b>
</a>


XSL: (I will determine the level of nesting for /a/b[2]

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:variable name="level">
 <xsl:apply-templates select="b"/>
</xsl:variable>

<xsl:template match="/">
 <xsl:apply-templates select="/a/b[2]"/>
 <xsl:value-of select="$level"/>
</xsl:template>


<xsl:template match="b">
  <xsl:apply-templates select="descendant::*[not(*)]" mode="level">
   <xsl:sort select="count(ancestor::*)" order="descending"
data-type="number"/>
  </xsl:apply-templates>
</xsl:template>


<xsl:template match="*" mode="level">
 <xsl:value-of select="count(ancestor::*)"/>
 <xsl:text>~</xsl:text>
</xsl:template>

</xsl:stylesheet>


And the output is:
4~3~3~

(you must extract the first number, this is the maximum)




Best regards
Jirka
