Re: [xsl] How to efficently determine if a nodes exists with an attribute value other than those in a list
Subject: Re: [xsl] How to efficently determine if a nodes exists with an attribute value other than those in a list From: David Carlisle <davidc@xxxxxxxxx> Date: Tue, 7 Aug 2007 17:42:28 +0100 |
> <xsl:variable name="tcheck"><xsl:sequence > select="'x',y','z'"/></xsl:variable> xsl:variable with no as or select attribute always creates a document node, so here $tcheck is a document node with a child text node with string value 'x y z' what you want is <xsl:variable name="tcheck" select="'x',y','z'"/> which gives you a sequence of strings, but then @type except $tcheck except is set difference, using _node identity_ as the test. As you had it it's the same as @type as it is the sequece 9of 1) type attribute nodes, minus the document node in $tcheck. Once $tcheck is a sequence of strings you'd get a type error as execpt needs node sequences. doc/*[(not(@type=$tcheck))] is your friend (or not depending on whether a node not having a type attribute at all is a possibility, and what you want in that case) David ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
