http://nagoya.apache.org/bugzilla/show_bug.cgi?id=20531 Variables not supported in <sort> ------- Additional Comments From [EMAIL PROTECTED] 2003-06-06 12:44 ------- Hmm... It seems that you are right. I had been fooled by the fact that THIS version (where I've declared the variable immediately before the <sort> but didn't USE it in the sort): <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";> <xsl:template match="/"> <TopNode> <xsl:for-each select="."> <xsl:variable name="foo" select="'bar'"/> <xsl:sort select="'abc'"/> <InnerNode/> </xsl:for-each> </TopNode> </xsl:template> </xsl:stylesheet> DID work, (and technically shouldn't have). So I guess this is not a valid bug. Unfortunately, it doesn't solve my problem, which now turns out to be a flaw in the design of XSLT, not in the apache implementation. I have a document structured like this: <Top> <SortCriteria> <Criterion order="2">abc</Criterion> <Criterion order="1">def</Criterion> <Criterion order="3">ghi</Criterion> </SortCriteria> <Data> <Datum otherInfo="ipso">abc</Datum> <Datum otherInfo="post">def</Datum> <Datum otherInfo="facto">ghi</Datum> </Data> </Top> What I want is to do a <for-each> in which I loop through the <Datum> elements, sorted according to the order attribute in the corresponding <Criterion> element. Something like this would do it: ... <xsl:for-each select="/Top/Data/Datum"> <xsl:variable name="datum-value" select="string(.)"/> <xsl:sort select="/Top/Criteria/Criterion[.=$datum-value]/@order"/> Template Here <xsl:value-of select="@otherInfo"/> </xsl:for-each> ... but unfortunately, it's not legal. Sorry for the erronious bug report. I'll seek another solution -- looks like XSLT isn't up to this task. -- Michael Chermside
