How to merge two XML documents into one?

[Anuj Seth <an...@sasi.com>]

Hi,

I have two XML documents (actually, RDF documents) and need to combine
them into one single document.

The following features are required,

Lets assume that the 1st file is called 1.xml and the second is called
2.xml

1. If a particular attribute with different values is present in both
the files, the one in 2.xml should be taken.

2. If 2.xml has an attribute not present in 1.xml it should be added to
the combined document.

I'm very new to Xerces-C and don't know how to go about doing the above.
I did go through the examples and have figured out how to read an XML
document, but couldn't figure out how to combine two documents.

Any help will be greatly appreciated.

Thank you,

With Regards,
Anuj

you will have to do the combining yourself.  my suggestion is to read both
documents into a DOM tree using the DOMParser.  Traverse document 2 and
modify document 1 while traversing #2.  Make multiple passes if you need.
After applying the rules you want from document 2 to document 1, doc 1 will
be your combined doc.  you can then output doc 1 through an XML Serializer.
