Shankar -
Good to hear from you.
Here is a bit of code:
def test(inFilename):
root = parse(inFilename)
person_list = root.get_person()
person_count = len(person_list)
print 'There are %d people in this document.' % (person_count, )
person1 = person_list[0]
name = person1.get_name()
print 'The name of the first person is: %s' % (name, )
> for example: from the below xml file i want to know

Since the <person> elements are a list, you can use len() to get a
count. Whenever a child is defined wth maxOccurs="unbounded" (or
maxOccurs greater than 1), the child is represented as a list.

You can use the getter and setter methods in the generated class to
access the children and attributes of an element. So, for example,
to get the name of a person, use:
name = person.get_name()
You will want to look at the code generated for some sample element
and compare that with the definition of the element/type in the XML
schema. Once you have looked at a couple of these generated
classes, you will see that they are all pretty much the same and
are reasonably predictable. In particular, for any attribute or
child named "abc" of an element/type, the class generated for that
element will contain methods get_abc() and set_abc() and, if it is
a list, add_abc(). Also look at the methods export(),
exportAttributes(), and exportChildren(), which give examples of
accessing the
I've attached a bit of a more complete example.
Hope this helps.
Let me know if I can be of more help.
