ALL,
For example,
<element>
<A/>
<B/>
<A/>
<C/>
<C/>
<D/>
</element>
I want to get the position first element whoes name is not A and B, but C & D. So it's 4 for this tree segment. How can I write the xslt to figure out this ?
Thanks,
Chen Yi

This will do but I'm sure there's a more elegant solution:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <xsl:value-of select="count((element/*[name() = 'C' or name() = 'D'])[1]/preceding-sibling::*) + 1"/> </xsl:template> </xsl:stylesheet>

One trap, if there aren't any matches this will give the wrong result, you may wish to test for any matches first: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/"> <xsl:variable name="CDnode" select="(element/*[name() = 'C' or name() = 'D'])[1]"/> <xsl:choose> <xsl:when test="$CDnode"> <xsl:value-of select="count($CDnode/preceding-sibling::*) + 1"/> </xsl:when> <xsl:otherwise> No matches </xsl:otherwise> </xsl:choose> </xsl:template> </xsl:stylesheet>
