Re: [xsl] pairing up similar tags based on an attribute

[George Cristian Bina <george@xxxxxxxxxxxxx>]

Hi,

It is not very clear for me what is your input and what is your 
output... Anyway, have a look at the following stylesheet, on your 
example it will output

pair(9300033,9300133) with common parent 9310079
pair(9300033,9300133) with common parent 9310023

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:key name="specByParent" match="spec" use="@parentpn"/>
  <xsl:template match="spec[@partnumber=9300033]">
    <xsl:variable name="specs" select="key('specByParent', @parentpn)"/>
    <xsl:text>pair(9300033,</xsl:text>
    <xsl:value-of 
select="$specs[generate-id()!=generate-id(current())]/@partnumber"/>
    <xsl:text>) with common parent </xsl:text>
    <xsl:value-of select="@parentpn"/>
  </xsl:template>
  <xsl:template match="spec"/>
</xsl:stylesheet>

Hope that helps,
George
