Case Insensitive findall in Python ElementTree

Question

I have to parse XML that has tag names that may be in any case (mixed, upper, lower, etc) and I don't know what the case will be beforehand. How can I make findall be totally case insensitive in ElementTree?

   # Does not work
   variables = message.findall("VaRiAbLE")

You simply get the string from the tree, lowercase it, and remake the tree. Then it should be parseable

import xml.etree.ElementTree as ET
def to_parseable(tree):
    t = ET.tostring(tree)
    t = t.lower()
    return ET.fromstring(t)
