Subject: [xsl] match selection formulae From: roger.day@xxxxxxxxxxxxxxxxxx Date: Fri, 7 Sep 2001 09:58:01 +0100 |
I suspect that this is a newbie question, but I could nott find the answer in the Big Red Book 2 or a trawl through the archives. I solved the problem in a kludge-like manner but I'm interested in teh reasons -why- it failed. I had a selection formula so; <xsl:template match="lg[@type='stanza' | @rend='italic']"> </xsl:template> <xsl:template match="lg[@type='stanza' | @rend='']"> </xsl:template> In my naiveity, I thought that @rend='' would be the equivalent of testing for the non-existence of an attribute - however, not(@rend) doesn't appear to work either. I'm using Xalan 2. what's the correct way for testing for the non-existence of an attribute (or an element come to that)? More distressingly, the first template always got ignored, not matter what pattern I tried with the second. Why did it fail? I "solved" the problem with a choose element inside a template matched for @type='stanza', but I'm interested on any solutions that would solve this problem in a more elegant manner.
