Subject: AW: AW: [xsl] for-each with included variable From: "Machelett, Renato (FA.G+M-EP/ETK)" <fa-gm-renato.machelett@xxxxxxxxxxxxxxxxxxx> Date: Thu, 19 Apr 2001 17:24:00 +0200 |
Hi David, Thank you for your comment, but I don't think I'm getting it. The situation is the following: I have that variable declared at global scope (at least I assumed I did when including it), so the content cannot change - at least that's how I understood the concept of XSL variables. As long as I'm not going out of scope it will have the value it initially had. <xsl:include href="IncludeMe.xsl"/> <!-- $myOPTypeList declared here --> <xsl:template select="/"> <xsl:for-each select="Whatever"> <xsl:for-each select="$myOPTypeList"> <!-- do some stuff --> </xsl:for-each> </xsl:for-each> </xsl:template> So I think what changes is the nodeset that is retrieved when applying the content of the variable, not the content of the variable itself. Or is that wrong? What I cannot see - due to my poor knowledge of XPath - is the semantic difference between: <xsl:for-each select="(.//*[@OPTypeRef='Type1'])[1] | (.//*[@OPTypeRef='Type2'])[1] | (.//*[@OPTypeRef='Type3'])[1]"> <!-- do some stuff --> </xsl:for-each> and <xsl:variable name="myOPTypeList">XType1,XType2,XType3</xsl:variable> <!-- global variable again --> <xsl:for-each select="(.//*[@OPTypeRef[contains($myOPTypeList, .)]])[1]"> <!-- do some stuff --> </xsl:for-each> And there must be a difference because the output is not the same.
