 I have a problem with a recursion and I don't have a clue, why my solution does not work. I did not find anything on the web, so your help is greatly appreciated. The problem: I need to perform an XML to XML transformation to augment the data with unique keys. The structure is as follows: <transformation> <IRF> <HEADER> <REC_IR020_01 index="1"> <UNB_S002_0004>16</UNB_S002_0004> ... </REC_IR020_01> <REC_IR030_01 index="1"> <UNH_0062>03081402160553</UNH_0062> ... </REC_IR030_01> ... </IRF> <id_list> <id>2003-08-25 15:36:59.534096</id> ... </id_list> </transformation> I do not know all tag names, but I know that I have some elements with an index attribute, which I need to transform to <REC_IR020_01> <id>2003-08-25 15:36:59.534096</id> <UNB_S002_0004>16</UNB_S002_0004> ... </REC_IR020_01> So I have to strip the index attribute and fetch one unique id from the id_list for each occurence of an index attribute. My Solution: I thought it's startightforward with XSL. My code: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan="http://xml.apache.org/xslt"> <xsl:output method="xml" indent="yes" encoding="UTF-8" omit-xml-declaration="no" xalan:indent-amount="2" /> <xsl:strip-space elements="*"/> <xsl:template match="/transformation"> <xsl:apply-templates select="IRF"/> </xsl:template> <xsl:template match="IRF"> <xsl:copy> <xsl:copy-of select="@*"/> <xsl:apply-templates select="descendant::*"/> </xsl:copy> </xsl:template> <xsl:template match="node()"> <xsl:param name="idCount" select="1"/> <xsl:choose> <xsl:when test="@index"> <xsl:copy> <xsl:element name="test"><xsl:value-of select="$idCount"/></xsl:element> <xsl:call-template name="addIdElement"> <xsl:with-param name="idCount" select="$idCount"/> </xsl:call-template> <xsl:apply-templates select> <xsl:with-param name="idCount" select="$idCount + 1"/> </xsl:apply-templates> </xsl:copy> </xsl:when> <xsl:otherwise> <xsl:copy> <xsl:apply-templates> <xsl:with-param name="idCount" select="$idCount"/> </xsl:apply-templates> </xsl:copy> </xsl:otherwise> </xsl:choose> </xsl:template> <xsl:template name="addIdElement"> <xsl:param name="idCount"/> <xsl:element name="id"> <xsl:copy-of select="/transformation/id_list/id[$idCount]"/> </xsl:template> </xsl:stylesheet> My problem is that the lines <xsl:apply-templates select> <xsl:with-param name="idCount" select="$idCount + 1"/> </xsl:apply-templates> do not call the template with the inceremnted parameter, so it always runs with the default value 1. Any ideas where my brain is scrumbled? Volker. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
