Re: Looking up keys in a separate xml file

Your one XSLT stylesheet can match nodes from different documents just by saying:

<xsl:template match="descriptions">......

Where elsewhere in your document you do the push:

<xsl:apply-templates select="document('thedocument.xml')/descriptions"/>

If you have a <descriptions> element in both input files, then you could either use modes or you could qualify an ancestral element that is unique in each file.

I tried that a number of different ways, but still had to fall back to the multiple pass methods... So I'm clearly not understanding...

T:\ftemp>type scott.xml
<Items>
<Item><Name>Item A</Name><InsertDescription lookup="a" /></Item>
<Item><Name>Item B</Name><InsertDescription lookup="b" /></Item>
<Item><Name>Item C</Name><InsertDescription lookup="a" /></Item>
<Item><Name>Item D</Name><InsertDescription lookup="c" /></Item>
<Item><Name>Item E</Name><InsertDescription lookup="a" /></Item>
</Items>

T:\ftemp>type scott.xsl
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:key name="descriptionlookup"
         match="Descriptions/Description"
         use="@name"/>

<xsl:template match="Items|Item|Name">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="InsertDescription">
  <xsl:variable name="lookup" select="@lookup"/>
  <xsl:for-each select="document('thedocument.xml')">
    <xsl:copy-of select="key('descriptionlookup',$lookup)"/>
  </xsl:for-each>
</xsl:template>

T:\ftemp>type scott.out
<?xml version="1.0" encoding="utf-8"?>
<Items>

   <Item>
      <Name>Item A</Name>
      <Description name="a">
         <Para>Description for <subname/>With Lookup Name A</Para>
      </Description>
   </Item>

   <Item>
      <Name>Item B</Name>
      <Description name="b">
         <Para>Description for <subname/>With Lookup Name B</Para>
      </Description>
   </Item>

   <Item>
      <Name>Item C</Name>
      <Description name="a">
         <Para>Description for <subname/>With Lookup Name A</Para>
      </Description>
   </Item>

   <Item>
      <Name>Item D</Name>
      <Description name="c">
         <Para>Description for <subname/>With Lookup Name C</Para>
      </Description>
   </Item>

   <Item>
      <Name>Item E</Name>
      <Description name="a">
         <Para>Description for <subname/>With Lookup Name A</Para>
      </Description>
   </Item>

</Items>
