In Python, is there an easy way to edit xml in place?

Suppose I want to edit a node in xml and edit one of its attributes. I want to be able to do a simple file diff to just see one row changed. Dumping the xml using prettyprint changes the whole xml structure.

Consider NOT using "a simple file diff". See this SO question.

Well then don't use prettyprint.

In xml.dom.minidom for example, if you do

doc = xml.dom.minidom.parse(inputfile)
do_something_with(doc)
outputfile.write(doc.toxml("utf-8").decode("utf-8"))

all the structure/whitespace etc. will remain unchanged.
