[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] inconsistent Preceding-Sibling behaviour when nested i
 I've observed a reproducible XSL behaviour that I just can't understand. "preceding-sibling", "following-sibling", and conditional expressions based on these axes appear to behave oddly when placed in a "for-each" element. My observations of the unusual behavior within the "for-each" loop: -- "following-sibling" behaves exactly as I would expect -- "preceding sibling" unexpectedly always refers to the first sibling in the document -- "if" statements behave erraticly: neither comparisons of current nodes to "preceding-sibling" nor comparisons to "following-sibling" appear to work completely. I've listed some sample code below to demonstrate the problem. Thanks much for any help with this. --Alan Example: My XML file: <joblist> <person> <name>frank</name> <job>cook</job> </person> <person> <name>frank</name> <job>clean</job> </person> <person> <name>joe</name> <job>drive</job> </person> <person> <name>chris</name> <job>clean</job> </person> <person> <name>chris</name> <job>drive</job> </person> </joblist> My XSL file: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"> <xsl:template match="joblist"> <xsl:for-each select="./person"> ++++++++++++++++++++++++++++ <br/> CurName=<xsl:value-of select="./name"/><br/> CurJob=<xsl:value-of select="./job"/><br/> <br/> PrevName=<xsl:value-of select="./preceding-sibling::node()/name"/><br/> PrevJob=<xsl:value-of select="./preceding-sibling::node()/job"/><br/> NextName=<xsl:value-of select="./following-sibling::node()/name"/><br/> NextJob=<xsl:value-of select="./following-sibling::node()/job"/><br/> <br/> <xsl:if test="./name=./preceding-sibling::node()/name">Name Match with Previous<br/></xsl:if> <xsl:if test="./name=./following-sibling::node()/name">Name Match with Next<br/></xsl:if> <xsl:if test="./job=./preceding-sibling::node()/job">Job Match with Previous<br/></xsl:if> <xsl:if test="./job=./following-sibling::node()/job">Job Match with Next<br/></xsl:if> </xsl:for-each> </xsl:template> </xsl:stylesheet> The Unexpected Output: ++++++++++++++++++++++++++++ CurName=frank CurJob=cook PrevName= PrevJob= NextName=frank NextJob=clean Name Match with Next ++++++++++++++++++++++++++++ CurName=frank CurJob=clean PrevName=frank PrevJob=cook NextName=joe NextJob=drive Name Match with Previous Job Match with Next ++++++++++++++++++++++++++++ CurName=joe CurJob=drive PrevName=frank PrevJob=cook NextName=chris NextJob=clean Job Match with Next ++++++++++++++++++++++++++++ CurName=chris CurJob=clean PrevName=frank PrevJob=cook NextName=chris NextJob=drive Name Match with Next Job Match with Previous ++++++++++++++++++++++++++++ CurName=chris CurJob=drive PrevName=frank PrevJob=cook NextName= NextJob= Name Match with Previous Job Match with Previous XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
