RE: [xsl] Duplicate elements. HELP!

Thanks Michael,

It works perfectly.

I had also gotten around to:
	<xsl:for-each select="CompanyResults/CompanyResult[not
           (CompanyTitle=preceding::CompanyTitle)]">

Which seems to work as well. But your solution is more succint since I am interested in siblings (same level) only and not ancestors, for example.

Thanx again!
Max

Your wrote

	<xsl:for-each select="CompanyResults/CompanyResult[not
 
(./CompanyTitle=preceding::CompanyResults/CompanyResult/CompanyTitle)]">


No CompanyResult has a preceding CompanyResults, because ancestors of an
element are not included on the preceding axis. Even if they were, this
condition wouldn't work because the CompanyResult children of the
CompanyResults include the element you started from, which is always equal
to itself. 

You want
 
	<xsl:for-each select="CompanyResults/CompanyResult[not
           (CompanyTitle=preceding-sibling::CompanyResult/CompanyTitle)]">
