Subject: [xsl] Varied Results with Different Versions of Xalan, But How? From: "Renick, Garrel" <garrel@xxxxxxxx> Date: Thu, 23 Aug 2007 11:32:28 -0500 |
I have an odd problem that seems unexplainable. I'm seeing different results of a simple transformation using xalan-j_2_6_0 (and prior versions) versus xalan-j_2_7_0. The xalan-j_2_7_0 version results in duplicated output. I'm using jdk1.5.0_12. Here are examples: XML: <?xml version='1.0'?> <document> <permission> <grp gid="101" name="group1"/> <grp gid="102" name="group2"/> </permission> </document> XSLT: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output method="html" omit-xml-declaration="yes"/> <xsl:variable name="theData" select="/document/permission"/> <xsl:template match="/document"> <xsl:variable name="grpcount" select="count($theData/grp)"/> <xsl:call-template name="makeGroupList"> <xsl:with-param name="groupSize" select="$grpcount"/> </xsl:call-template> </xsl:template> <xsl:template name="makeGroupList"> <xsl:param name="groupSize"/> <select name="selectName" size="{$groupSize}" multiple="true"> <xsl:apply-templates select="$theData/grp"> <xsl:sort select="@name"/> </xsl:apply-templates> </select> </xsl:template> <xsl:template match="grp"> <xsl:variable name="gid" select="./@gid"/> <option value="{$gid}"><xsl:value-of select="@name"/></option> </xsl:template> </xsl:stylesheet> Output xalan-j_2_7_0: <select multiple="true" size="2" name="selectName"> <option value="101">group1</option> <option value="101">group1</option> <option value="102">group2</option> <option value="102">group2</option> </select> However, the output from j_2_6_0 is as expected: Output xalan-j_2_6_0: <select multiple="true" size="2" name="selectName"> <option value="101">group1</option> <option value="102">group2</option> </select> If I comment out the grpcount variable definition and pass a param with a literal value in the call to the makeGroupList template, both versions of xalan produce the same output. I'd appreciate any insight into why this is happening. Regards, Garrel Renick
