Subject: [xsl] document() and key() boundaries. From: <anne.kootstra@xxxxxxxxxxxxx> Date: Wed, 21 Mar 2007 16:27:57 +0100 |
Dear experts. The application I'm working on is one to generate a letter from two xml files utilising xslt. The base.xml file contains all the information about the person who the letter is intended for. In the detail.xml standard text fragments are stored that make up the letter. The xslt file processes the tags in the base.xml file and grabs the relevant text fragments from the detail.xml file using the document() function. The problem I'm facing is that some of the text fragments in the detail.xml file have a reference to fields in the base.xml document. However, I've been unable to cross the boundary from detail.xml back into the base.xml using the key() function. In the included example there is a text fragment that requires the inclusion of the first name of the father. The end result is that the name "Klaas" is included, however I intended to include the name "Bert". The only reason the father's details are also present in the detail.xml is to prove the fact that the technique works, but that it searches the wrong document. In real live this information would not be present in detail.xml. Base.xml --------------------------------------------------- <?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="style.xsl" version="1.0"?> <paragraphs> <ContactRelationship> <FirstName>Bert</FirstName> <RelationshipType>Vader</RelationshipType> </ContactRelationship> </paragraphs> ---- Detail.xml --------------------------------------------------- <?xml version="1.0" encoding="ISO-8859-1"?> <paragraphs> <paragraph>Parent name is: [<relation type="Father"/>] [This should be Bert]</paragraph> <ContactRelationship> <FirstName>Klaas</FirstName> <RelationshipType>Father</RelationshipType> </ContactRelationship> </paragraphs> ---- Style.xls --------------------------------------------------- <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:key name="Test_A" match="ContactRelationship" use="RelationshipType" /> <xsl:template match="/"> <xsl:call-template name="template"/> </xsl:template> <xsl:template match="paragraph"> <xsl:apply-templates /> </xsl:template> <xsl:template match="relation"> <xsl:value-of select="key('Test_A',@type)/FirstName"/> </xsl:template> <xsl:template name="template"> <xsl:apply-templates select="document('detail.xml')/paragraphs/paragraph"/> <xsl:for-each select="document('detail.xml')/paragraphs/paragraph"> <xsl:apply-templates select="." /> </xsl:for-each> </xsl:template> </xsl:stylesheet> ---- In the included example I have used two scenarios I've tested and re-tested. There is one additional thing worth mentioning: the file name of the base.xml is variable. It is therefore not possible to create a direct document() link between the detail.xml and the base.xml. Hopefully someone can help me with this particular situation. It appears that the focus is locked to the detail.xml document and that is why "Klaas" is included. Anyone having any suggestions on how to include the name "Bert"? The intended version of XSLT is 1.0 however, if 2.0 might be the working solution I would be curios to know that too. The processor for the job is at this point msxsl.exe. Which I believe is based upon version 4.0 of MSXML. Any and all suggestions are appreciated.
