Parsing xml is a relatively standard problem, you can have a look at this: https://docs.python.org/2/library/xml.etree.elementtree.html

Alternatively, BeautifulSoup is a nice library to parse html and xml: http://www.crummy.com/software/BeautifulSoup/bs3/documentation.html

Some more info about BeautifulSoup in a previous question: Python BeautifulSoup XML Parsing

Thanks...

for parsing xml i use recurse becous is better

import xml.etree.ElementTree as etree
tree = etree.parse('asd.xml')
root = tree.getroot()

def recurse_children(node):
    for children in node:
         if len(children) > 0:
            recurse_children(children)
        print children.tag, children.attrib, children.text
    print ('\n')

for child in root:
    recurse_children(child)

I looking in this BeautifulSoup from yesterday but still don't get it... is anyone that could help?
