Updating an XML file

Hi Guys, any recommendations for the following -

Have a "settings" XML file with things like

<settings>
<something>TRUE</something>
<somethingelse>FALSE</somethingelse>
</settings>

In a new version of the App, I want to include a new default
"settings" file, adding a couple of new nodes, and "merge" the
existing settings file with the new one, whilst maintaining any
existing settings. Basically, compare the new default file to the
existing file and add/remove any nodes based on what's in the new
format.

Now obviously I can do this manually in the code, but do there exist
any clever XML commands/functions to do this merge automagically?
