Change XML value using Code Synthesis c++

I need to change some values of an existing XML using Code Synthesis in c++.

For example i have this:

<person>
  <name>"Paul"</name>
</person>

Now i need to change it to "Chris".

I have used several time Code Synthesis for parsing but never to write into a XML.

p.s Yes i've compiled my XSD with "Generate Serialization" option.

Thank you
