Replacing XML Nodes in Java

Question

I have an XML document in a foreign language and another XML document in English. I am trying to replace some nodes in the foreign document with nodes from the English document and export the document.

I have been working on this for days now and have tried countless things form importing both documents into text with a Scanner, BufferedReader, etc. with no good results.

I'm at a loss on what else I can try. I have searched for days and have nothing. Maybe what I'm trying to do cannot be done although it seems simple enough. Any help/direction would be appreciated.

Not sure why this was closed as it was a clear question with a correct, and accepted answer. — Droid, May 31 '14 at 01:50

Put them into DOM objects, then use XPATH to locate and select nodes, to copy values between them.

Depending on what you need to replace and what you mean by "export", I would use an XML parser like SAX using the following algorithm

For each node that you read
    Replace attributes or text as necessary
    Write it out to the the a new XML file

There are many tutorials out there on how to use SAX, such as this one: How to parse XML using the SAX parser

If the "replacements" you need to do are very straightforward like "all <tag> objects under <parent-tag>" then maybe building the DOM and using XPath would work, but if your replacements are very arbitrary and unstructured then I'd go with parsers.
