Assuming that you've parsed the XML and have a DOM. What you need to do is:

1. Delete the existing text node from the <doc> element.

2. Insert the a text node consisting of the first part of the text into the <doc> element.

3. Insert an element node for the <b> element into the <doc> element.

4. Insert the text content into the <b> element.

5. Insert the a text node consisting of the remainder of the text into the <doc> element.

I believe that in such simple scenarios all you need to do, is to convert the xml into a string and perform a "string replace". This would involve much less code. But if you are restricted to working in xml format, then follow the instructions provided by @Stephen C, using any api e.g jdom
