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 total

Answer 1

Regex to the rescue. Note this is probably horrific in terms of performance but is great at extracted XML attributes from elements.

def getInsensitiveAttrbiute(element, key) :

   keyRegex = re.compile(key, re.IGNORECASE)
   for key in element.attrib.keys() :
       if keyRegex.match(key) :
           return element.attrib[key]
   raise KeyError


element = ET.fromstring('')
print getInsensitiveAttrbiute(element, "sRc")
