The ElementTree.parse reads from a file, how can I use this if I already have the XML data in a string?
Maybe I am missing something here, but there must be a way to use the ElementTree without writing out the string to a file and reading it again.

If you're using xml.etree.ElementTree.parse to parse from a file, then you can use xml.etree.ElementTree.fromstring to get the root Element of the document. Often you don't actually need an ElementTree.
You need the xml.etree.ElementTree.fromstring(text)
from xml.etree.ElementTree import XML, fromstring
myxml = fromstring(text)
io.StringIO is another option for getting XML into xml.etree.ElementTree:
import io
f = io.StringIO(xmlstring)
tree = ET.parse(f)
root = tree.getroot()
Hovever, it does not affect the XML declaration one would assume to be in tree (although that's needed for ElementTree.write()). See How to write XML declaration using xml.etree.ElementTree.
