You meant name()='subcategory' with quotes 3. ./*[name()='subcategory'] is a long-winded way of writing ./subcategory 4. The guy wants to know if the subcategory element exists, not if it has non-empty text content. 5. Why test the same condition twice, rather than using xsl:choose? Try instead: <xsl:choose> <xsl:when test="subcategory">Success</xsl:when> <xsl:otherwise>Failure</xsl:when> </xsl:choose> Michael Kay Software AG home: Michael.H.Kay@xxxxxxxxxxxx work: Michael.Kay@xxxxxxxxxxxxxx > > > > > -----BEGIN PGP SIGNED MESSAGE----- > > Hash: SHA1 > > > > I have an XML file that contains the following structure: > > > > <category> > > <subcategory> > > <article> > > </article> > > </subcategory> > > </category> > > > > In my XSLT stylesheet, I need to be able to test if the <category> > > node I'm working with contains a <subcategory> node.
