With any XML tree API, be it DOM or lxml or ElementTree or Amara or whatever, 
you are working with an in-memory model of the document. This model was 
derived from the original serialized XML (the file) at parse time. Changes to 
the model are confined to the model; they're in memory only. When you're done 
making changes, you should produce a new serialization; the means of doing 
this varies depending on the API you're using, but you can surely search 
through the API docs or tutorials for how to serialize the tree. You can put 
that serialization into a file, overwriting the old file if you want.

I won't, but would maybe someone else is feeling more charitable.
