For future reference, I suggest raising this sort of question on the XSL-List[1] instead. XSLT/XPath 1.0 doesn't provide a generalized form of what you want, so you'll have to craft your XPath expressions on a case-by-case basis. This particular example is pretty easy to solve. <xsl:for-each select="/TAG1/TAG2[not(.=preceding::TAG2)]">... The current form[2] may change, but XQuery/XPath 2.0 will in any case provide a generalized mechanism for doing this. Hope this helps! Evan Lenz XYZFind Corp.
