Personally I'd use something like the python BeautifulSoup module to
do all the work. It's really forgiving when it comes to dealing with
poorly formed xml or html and makes it easy to pull information out of
pretty much any html/xml document.
Docs are here: http://www.crummy.com/software/BeautifulSoup/documentation.html

>>> import BeautifulSoup
>>>
>>> xml = """
... <first id="34">
... blah blah
... <second id="56" name="xyz1">hello hello</second>
... <second name="xyz4">hello hello</second>
... <second id="16" name="xyz5">hello hello</second>
... <first id="3">
... blah blah blah
... <second>hello hello</second>
... <second id="12" name="xyz5">hello hello</second>
... """
>>> soup = BeautifulSoup.BeautifulStoneSoup(xml)
>>> print soup.prettify()
<first id="34">
 blah blah
 <second id="56" name="xyz1">
  hello hello
 </second>
 <second name="xyz4">
  hello hello
 </second>
 <second id="16" name="xyz5">
  hello hello
 </second>
</first>
<first id="3">
 blah blah blah
 <second>
  hello hello
 </second>
 <second id="12" name="xyz5">
  hello hello
 </second>
</first>
>>> soup.findAll('second')
[<second id="56" name="xyz1">hello hello</second>, <second
name="xyz4">hello hello</second>, <second id="16" name="xyz5">hello
hello</second>, <second>hello hello</second>, <second id="12"
name="xyz5">hello hello</second>]
>>> for item in soup.findAll('second'):
...     print item
...
<second id="56" name="xyz1">hello hello</second>
<second name="xyz4">hello hello</second>
<second id="16" name="xyz5">hello hello</second>
<second>hello hello</second>
<second id="12" name="xyz5">hello hello</second>
