There are a couple of ways:

1.  Use DOM

from xml.dom.ext.reader import PyExpat
reader = PyExpat.Reader()

dom = reader.fromString(XML_SRC)

flds = dom.documentElement.getElementsByTagName('fld')

for f in flds:
    print fld.getAttribute('id')
    print fld.firstChild.data


2.  Use XPath

from xml import xpath
from xml.dom.ext.reader import PyExpat
reader = PyExpat.Reader()

dom = reader.fromString(XML_SRC)

flds = xpath.Evaluate('//fld',contextNode = dom)

for f in flds:
    print fld.getAttribute('id')
    print fld.firstChild.data
