Can I append an XML Document into another?

Question

I have a large xml document which I open into coldfusion (mx
7), and then a smaller group of files that are opened into thier
own xml objects. After some customization of xml text values, I
want to append the smaller xml documents into the larger document
at specific positions within the document tree.
I have the code that I thought would do this, using an
arrayappend function, but what happens is that only the root
element of the smaller (inserted) xml document is placed into the
main document.
Is this possible, or do I need to modify the code so that the
entire tree of xml data that I am appending is created on the
fly?

Answer 1

Personally I do this with XSLT.
<cfxml variable="doc1">
<root>
<member id="10">
<name>Ian</name>
<sex>male</sex>
</member>
</root>
</cfxml>
<cfxml variable="doc2">
<root>
<member id="1">
<name>Joe</name>
<sex>male</sex>
</member>
<member id="2">
<name>John</name>
<sex>male</sex>
</member>
<member id="3">
<name>Sue</name>
<sex>female</sex>
</member>
</root>
</cfxml>
<cffile action="write" file="#expandPath("/")#\doc2.xml"
output="#ToString(doc2)#" nameconflict="overwrite">
<!--- METHOD ONE using a depreciated and undocumented
method --->
<cfset newNode = doc1.root.member.cloneNode(true)>
<cfset doc2.changeNodeOwner(newNode)>
<cfset doc2.root.appendChild(newNode)>
<cfdump var="#doc2#" label="Merged by hidden functions"
expand="no">
<!--- METHOD TWO using XSLT --->
<!--- create an xsl docutment--->
<cfoutput>
<cfsavecontent variable="transformer">
<xsl:stylesheet xmlns:xsl="
http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml"/>
<!--load the merge file -->
<xsl:variable name="emps"
select="document('#expandPath("/")#\doc2.xml')"/>
<!--- this line references and XML file to be combined
with the main file,
I wonder if there is a way to use an XML document in memory
here? --->
<!-- combine the files -->
<xsl:template match="/">
<root>
<!-- select all the child nodes of the root tag in the
main file -->
<xsl:for-each select="root/child::*">
<!-- copy the member tag -->
<xsl:copy-of select="."/>
</xsl:for-each>
<!-- and all the child nodes of the root tag in the merge
file -->
<xsl:for-each select="$emps/root/child::*">
<!-- copy the member tag -->
<xsl:copy-of select="."/>
</xsl:for-each>
</root>
</xsl:template>
</xsl:stylesheet>
</cfsavecontent>
</cfoutput>
<!--- create a combined xml document --->
<cfset doc2 = XMLparse(XMLtransform(doc1,transformer))>
<cfdump var="#doc2#" label="Merged by XSLT"
expand="no">
