Merging 2 documents using XSLT

Question

hi All,
I am new to XSLT. I am having two xml documents which will like the below:
document x
<ModelObject ParentID="1735313271" UniqueID="335539509" ext="kpi" fromServer="true">
<attr name="UniqueID" stringvalue="335539509" />
<attr ParentID="1735313271" name="ParentID" />
<attr name="fromServer" stringvalue="true" />
<attr name="index" stringvalue="1" />
<attr name="weight" stringvalue="10" />
<attr name="frequency" stringvalue="Yearly" />
<attr name="notes" stringvalue="" />
<attr name="datasource" stringvalue="" />
<attr name="intention" stringvalue="" />
<attr name="owner" stringvalue="" />
<attr name="object.name" stringvalue="kpi" />
</ModelObject>
document y
<ModelObject IsNew="false" ParentID="1735313271" UniqueID="335539509" ext="kpi" fromServer="true">
<attr name="index" stringvalue="1" />
<attr name="longtermgoaldeadline" stringvalue="25/05/2004" />
<attr name="datasource" stringvalue="" />
<attr name="frequency" stringvalue="Yearly" />
<attr name="owner" stringvalue="" />
<attr name="notes" stringvalue="testdefinition" />
<attr name="checkedoff" stringvalue="false" />
<attr name="units" stringvalue="Millions" />
<attr name="formats" stringvalue="" />
<attr name="IsNew" stringvalue="false" />
<attr name="intention" stringvalue="intention" />
<attr name="fromServer" stringvalue="true" />
<attr name="DecObjID" stringvalue="105" />
<attr name="object.name" stringvalue="kpi" />
<attr name="UniqueID" stringvalue="335539509" />
<attr name="weight" stringvalue="10" />
<attr name="ParentID" stringvalue="1735313271" />
</ModelObject>
Both the documents are slightly different that x may contain which are not in y and vice versa. I need to write a XSLT for merging these two documents and the result document should be the merged one with all the fields of x and y. Can anyone help me.
Thanks in advance.

And why did you think that a forum named "Java Programming" was the best place to ask this question? The Mulberry XSLT list would have been much better.
I would recommend using the document() function to access a second XML document, and the xsl:key element to search for elements in either of your two documents.
