This is job for xpath.

from xml import xpath
from xml.dom import minidom

doc = """<para role="success">1</para>"""

mydom = minidom.parseString(doc)
#result_nodes = xpath.Evaluate("/para/text()", mydom)
#result_nodes = xpath.Evaluate("/para[1]/text()", mydom)
result_nodes = xpath.Evaluate("/para[@role='success']/text()", mydom)
for ix, r in enumerate(result_nodes):
   print "result %d: %s" % (ix, r)
