Merge two xml documents

Hi,
  I have two xml documents stored as OracleXMLDocGenString objects doc1 & doc2, each of them generated through the qry.getXML() method. Now i want to merge the two documents into a third OracleXMLDocGenString Object doc.

I tried the method docAppend in OracleXMLDocGenString
like
doc.createNewDocument(true);
doc.docAppend(doc1);
doc.docAppend(doc2);
but this appends a null to my document doc instead of the xml.

The doc1.getXMLDocumentString() & doc2.getXMLDocumentString() returns the whole 347 records i have in my xml document and so i am sure the objects doc1 and doc2 are properly created.

Can anyone tell me how i can merge the two documents into one.

Thank you
Suresh

I suspect that the API definition of docAppend() takes a node list or an XML string and not a "document". I tried to find an API specification for the call on the Oracle site but they restrict passwords to 6-16 characters and Rat's don't like that!

So I would suggest you either try to post the API and/or try something along the lines :-

    doc.docAppend(doc1.document());
or
    doc.docAppend(doc1.getXMLDocumentString());

Thank you for the research. The API was defined for the parent class OracleXMLDocGen.
So i had to redefine the doc, doc1 and doc2 as OracleXMLDocGen instead of OracleXMLDocGenString and then populate them with the qry.getXML()
A Method newDocGenDoc helped me create a child node to be appended to the parent doc.

Oh dear! How complicated.

Well I'm not "au fait" with Oracle APIs but if the documents are not too big I would be tempted to convert them into strings, use a bit of script to put them together with a new <root> and stick the resultant document back into a DOM.

Thanks for returning and finalizing your questions.  Please let us know where we fell short of expectations, given you've assigned a "B" grade versus "A".  If this was in error, I can correct this.  Your points remains the same, but the expert points that flow are a direct result of the grades assigned.  If you found additional information outside this question thread, and can add it here, that will help others as they access this item looking for solutions in the future.
