title: Case Insensitive findall in Python ElementTree
body: <p>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?</p>
  
  <pre><code>   # Does not work
     variables = message.findall("VaRiAbLE")
  </code></pre>
