Subject: [xsl] How to efficently determine if a nodes exists with an attribute value other than those in a list From: "Peter Hunsberger" <peter.hunsberger@xxxxxxxxx> Date: Tue, 7 Aug 2007 11:27:56 -0500 |
Suppose I have a document with a bunch of nodes each with a type attribute, something like: <doc> <a type="x"/> <b type="y"/> . . . <z type="42"/> </doc> Using an XSLT 2 stylesheet I'd like to efficently determine if there are any nodes where the type attribute value is not in a list of given values. I thought I might be able to do this with a sequence and the except operator, but I haven't gotten it to work, the code basically looks like: <xsl:variable name="tcheck"><xsl:sequence select="'x',y','z'"/></xsl:variable> <xsl:if test="doc/*[@type except $tcheck]">got one</xsl:if> Which I suspect is attempting to check attributes against strings. Using Saxon 8 I don't get an error, but I also don't get a "got one" result. Any suggestions? -- Peter Hunsberger
