The purpose is to generate a single xml file in which I can apply an xsl
that we have that generates a matrix table comparrison of the two vehicles.
So its important that each vehicle have the same nodes whether empty or not.
In the example since the <header header_name="Misc"> node had the same row
nodes in both xml's that was not merged. If xml 2 has a header node that
xml1 does not have then that would have to be merged as well.
Here is my xsl at this point.
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output method="xml"/>
<xsl:template match="/">
<xsl:apply-templates select="vehicle" />
</xsl:template>
<xsl:template match="vehicle">
<xsl:variable name="xml2" select="document('xml2.xml')" />
<vehicles>
<vehicle>
<xsl:attribute name="aic_id"><xsl:value-of select="@aic_id"
/></xsl:attribute>
<make>
<xsl:apply-templates select="make" mode="copy" />
</make>
<year>
<xsl:apply-templates select="year" mode="copy" />
</year>
<model>
<xsl:apply-templates select="model" mode="copy" />
</model>
<style>
<xsl:apply-templates select="style" mode="copy" />
</style>
<image>
<xsl:apply-templates select="image" mode="copy" />
</image>
<headers>
<xsl:for-each select="$xml2//headers/header">
<xsl:if test="@header_name=$xml2//@header_name">
<xsl:variable name="bcheck">true</xsl:variable>
</xsl:if>
<xsl:if test="@bcheck='true'">

<xsl:attribute name="header_name"><xsl:value-of

----Original Message Follows----
From: Robin LaFontaine <robin.lafontaine@deltaxml.com>
You seem to have in your output a <vehicle> for each of the input <vehicle>
elements, but the <header name="Safety"> seem to have been merged in the two
cases, whereas the <header name="Misc"> is not merged. This suggests you
have very specific needs here.
One other small point: suggest you use xsl:strip-space to get rid of the
spurious indentation (perhaps the files are not indented in originals).
Hope this helps a little.
