Subject: [xsl] matching on multiple attributes contained in a node-set From: Carl Yu <carl.yu@xxxxxxxxxxxx> Date: Thu, 27 Mar 2003 18:11:48 -0800 (PST) |
Hi, This seems like super easy problem, that I'm overthinking. I really need some other eyeballs on it. I'm trying to match items contained in a node-set (stored in a variable in the xsl file). The trick is, the list contains sets of items that must be compared together. Here are the files... [in.xml] <?xml version="1.0" encoding="UTF-8"?> <dftml version="0.2"> <student> <name value="bob"/> <grade value="1"/> <type="lunch"/> </student> <student> <name value="joe"/> <grade value="1"/> <type="science"/> </student> <student> <name value="peter"/> <grade value="2"/> <type="math"/> </student> <student> <name value="larry"/> <grade value="1"/> <type="math"/> </student> </dftml> [test.xsl] <?xml version="1.0"?> <xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan="http://xml.apache.org/xalan" exclude-result-prefixes="xalan" version="1.0"> <xsl:output method="text"/> <xsl:variable name="list"> <item grade="1" type="math"/> <item grade="2" type="science"/> </xsl:variable> <xsl:template match="/node()"> <xsl:apply-templates select="/dftml/student"/> </xsl:template> <xsl:template match="/dftml/student"> <xsl:variable name="this" select="self::node()"/> <xsl:for-each select="xalan:nodeset($list)/item"> <xsl:variable name="item" select="self::node()"/> <xsl:element name="blah"> <xsl:choose> <xsl:when test="$this/grade/@value=$item/@grade and $this/type/@value=$item/@type"> <xsl:value-of select="$this/name/@value"/> <xsl:text> is in the list. </xsl:text> </xsl:when> <xsl:otherwise> <xsl:value-of select="$this/name/@value"/> <xsl:text> is not in the list. </xsl:text> </xsl:otherwise> </xsl:choose> </xsl:element> </xsl:for-each> </xsl:template> </xsl:transform [out.xml] bob is not in the list. bob is not in the list. joe is not in the list. joe is not in the list. peter is not in the list. peter is not in the list. larry is in the list. larry is not in the list. The desired output would list all the students, but only once. That is, larry is listed as being on the list, all others are not. The variable $list can be variable in length.. that is, I may add or remove items from this list (in fact, in the real-deal, this is a passed-in parameter to the Transformer.) When I first thought of this problem I though I could just use a simple match... why is the solution eluding me! Arrgh. In the case where there's only one item to match, this could be done using a simple match statement... the fact that there is a pair of items to match is tripping me up. Please help!
