[xsl] How to avoid duplicated items in result tree
Subject: [xsl] How to avoid duplicated items in result tree From: Ramnivas Laddad <ramnivas@xxxxxxx> Date: Tue, 29 May 2001 16:51:31 -0700 |
Hello, I am facing this problem of avoiding duplicate entries in the result tree. Can somebody please help? Given XML file such as follows: <?xml version="1.0"?> <structure> <element name="A_AB"> <superclass type="A"/> <superclass type="A_B"/> </element> <element name="A_B"> <superclass type="A"/> <superclass type="B"/> </element> <element name="A"/> <element name="B"/> <element name="X"/> </structure> I want to extract all direct and indirect superclasses of a given element (supplied as a parameter) I am trying the following stylesheet: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" indent="yes"/> <xsl:strip-space elements="*"/> <xsl:template match="/"> <elementDetails name = "{$elementToExtract}"> <xsl:call-template name="printElement"> <xsl:with-param name="elementName" select="$elementToExtract"/> </xsl:call-template> </elementDetails> </xsl:template> <xsl:template name="printElement"> <xsl:param name="elementName"/> <xsl:copy-of select="//element[@name=$elementName]"/> <xsl:for-each select="//element[@name=$elementName]/superclass"> <xsl:call-template name="printElement"> <xsl:with-param name="elementName" select="@type"/> </xsl:call-template> </xsl:for-each> </xsl:template> </xsl:stylesheet> This stylesheet produced follwing output for element A_AB: (Command: java org.apache.xalan.xslt.Process -in structure.xml -xsl extract.xsl -param elementToExtract A_AB ) <?xml version="1.0" encoding="UTF-8"?> <elementDetails name="A_AB"> <element name="A_AB"> <superclass type="A"/> <superclass type="A_B"/> </element> <element name="A"/> <element name="A_B"> <superclass type="A"/> <superclass type="B"/> </element> <element name="A"/> <!-- <<< I will like to avoid this duplicated entry --> <element name="B"/> </elementDetails> Can somebody suggest me a way to avoid duplicate entries (in above case, one of the element A) in the result tree. Thanks. -Ramnivas XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
