>Hi,
>
>I am trying to merge two xml files, using a xsl stylesheet. Those files are
>actually BEA Weblogic's configuration files (config.xml and a partial
>config.xml), but I'd like the xsl script to be quite generic (avoid
>hardcoding the element names and attributes).
>
>Basically, the only thing I know about the files is that they have the same
>root node.
>
>For example, with the 2 following files:
>File1.xml:
><root>
>	<elt1 att1="a" att2="b">
>		<subelt1 att1="b"/>
>		<subelt1 att1="c"/>
>	</elt1>
>	<elt2 att1="d"/>
></root>
>
>File2.xml:
><root>
>	<elt1 att1="a" att2="b">
>		<subelt1 att1="c"/>
>		<subelt1 att1="d"/>
>	</elt1>
>	<elt1 att1="a" att2="d">
>		<subelt1 att1="x"/>
>	</elt1>
>	<elt3 att1="e"/>
></root>
>
>Should give something like:
><root>
>	<elt1 att1="a" att2="b">
>		<subelt1 att1="b"/>
>		<subelt1 att1="c"/>
>		<subelt1 att1="d"/>
>	</elt1>
>	<elt1 att1="a" att2="d">
>		<subelt1 att1="x"/>
>	</elt1>
>	<elt2 att1="d"/>
>	<elt3 att1="e"/>
></root>
>
>So the following rules must be respected:
>. Each element associated with its attribute is unique (we don't have two
><elt1 att1="a" att2="b">).
>. If one element exists only in one of the file, it should  appear in the
>output.
>
>I am very new to xsl and tried to look on the web without finding exactly
>what I want.
>
>Does anyone have an idea on how to solve that question?

>Thank you,
