RE: [xsl] XPatch: ancestor and count

["Ivan Pedruzzi" <ipedruzz@xxxxxxxxxxxx>]

Andrey,

I slightly modified the XSLT like that

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="html"/>
<xsl:template match="menu">
  <table class="menu" border="1">
    <tr><td><xsl:value-of
select="count(ancestor::*)"/></td><td>&#xA0;</td></tr>
    <xsl:for-each select="descendant::menuitem">
     <tr><td><xsl:for-each select="ancestor::*">/<xsl:value-of
select="concat(local-name(), ' ', @title)"/></xsl:for-each></td><td>
     <xsl:value-of select="@title"/></td></tr>
    </xsl:for-each>
  </table>
</xsl:template>
</xsl:stylesheet>

I got consistent results with XalanJ, Saxon 6, Saxon 8, MSXML,
XslTransform.

0
/menu  					1
/menu  					2
/menu /menuitem 2 			2.1
/menu  					3
/menu /menuitem 3 			3.1
/menu /menuitem 3 			3.2
/menu /menuitem 3 			3.3
/menu /menuitem 3 			3.4
/menu /menuitem 3/menuitem 3.4 	3.4.1
/menu /menuitem 3/menuitem 3.4 	3.4.2
/menu /menuitem 3 			3.5
/menu /menuitem 3 			3.6
/menu /menuitem 3/menuitem 3.6 	3.6.1
/menu /menuitem 3/menuitem 3.6 	3.6.2

You may try with LibXSLT to see what path comes out.
