does the XML Task update XML files?

I'm using package configurations to store my server/database name in an XML File. I need to be able to dynamically change the database at runtime when I execute the package. Can I use the XML Task in another package to make a change to that xml file? I'm not familiar at all with XML, so I don't really know the syntax for XPath or XSLT or anything. Basically I'm just looking for an example of how to this with XML, but I haven't found anything on the web to explain this to me. BOL isn't very helpful with the XML Task.
I'm using the June CTP, but also have access to the Sept CTP.
Thanks,

If you save the results as a file, yes.
K|||but can I overwrite the source file? Do you have any examples of this or point me to one? I don't see on in BOL or in the Samples that come with the CTP's.
Thanks,
