Use the xml.etree.ElementTree module instead. It makes this kind of work
really easy, e.g.:
 import xml.etree.cElementTree as ET # using fast C accelerator module
 root = ET.parse("afile.xml").getroot()
 for child in root:
 if child.tag == 'abc':
 print("abc tag found")
 else:
 print("other tag found")
There's also an incremental iterparse() function, in case your documents
are large.
