iterparse() is too big a hammer for this purpose, IMO. How about this:

  from xml.etree.ElementTree import ElementTree
  tree = ElementTree(None, "myfile.xml")
  for elem in tree.findall('//book/title'):
      print elem.text

Thanks for the prompt reply .

I feel let me try using iterparse. Will it be slower compared to SAX
parsing ... ultimately I will have a huge xml file to parse ?

If you use the cElementTree module, it may even be faster.

Another question , I will also need to validate my xml against xsd . I
would like to do this validation through the parsing tool  itself .

In that case, you can use lxml instead of ElementTree.

Hi ,

Is lxml part of standard python package ? I am having python 2.5 .

I might not be able to use any additional package other than the
standard python . Could you please suggest something part of standard
python package ?

Thanks
