XML aggregation

["Morrison, John" <Jo...@uk.experian.com>]

Hi all,

I'm trying to aggregate two pieces of xml prior to applying a xsl
transformation to the results but all the combinations I've tried have come
to naught.  Could somebody please tell me if 1) its possible ;) and 2) how
to do it!.

<xsl:apply xsl="/WEB-INF/stylesheets/sample.xsl">
	<io:request url="one.xml"/>
	<io:request url="two.xml"/>
</xsl:apply>

I'd quite like to put the results of one.xml and two inside a seperate
element, eg

<aggregated>
	<one>
		<!-- one.xml contents -->
	</one>
	<two>
		<!-- two.xml contents -->
	</two>
</aggregated>

as I've got to mimic in JSP/tags something I'm currently doing in C2.

Many thanks for any ideas/help,

John.

Yes :-)

There's a few different ways.

In XSLT you can use the document() function to load other documents.

http://www.zvon.org/xxl/XSLTreference/Output/function_document.html


Or, if the 2 documents are static and do not have the <?xml version="1.0"?>
declarations then you could do this

<xsl:apply xsl="/WEB-INF/stylesheets/sample.xsl">
<aggregated>
<io:request url="one.xml"/>
<io:request url="two.xml"/>
</aggregated>
</xsl:apply>

If you have the documents locally as files you could just do this

<xsl:apply xsl="/WEB-INF/stylesheets/sample.xsl">
<aggregated>
<%@include file="one.xml" %>
<%@include file="two.xml" %>
</aggregated>
</xsl:apply>


Hopefully in a few days time you'll be able to do things like the following
in XTags (when some new code developed by James Elson is incorporated):-

<!-- create the composite document -->
<xtags:parse>
<aggregated/>
</xtags:parse>

<!-- append child documents to root element -->
<xtags:forEach select="/aggregated">
    <xtags:add>
        <io:request url="one.xml"/>
    </xtags:add>

    <xtags:add>
        <io:request url="two.xml"/>
    </xtags:add>
</xtags:forEach>

<!-- now style the composite document -->
<xtags:style xsl="/WEB-INF/stylesheets/sample.xsl"/>
