XML in Python

#import

from xml.dom import minidom

#parse file

xmldoc=minidom.parse('input.xml')

#get element by tag name

#xmldoc.getElementsByTagName('ID')

#element as list

#xmldoc.getElementsByTagName('ID')[0]

#get child node

#xmldoc.getElementsByTagName('ID')[0].childNodes[0]

#some example

#loop by all child nodes of element with name 'Fragments'

for i in reversed(xmldoc.getElementsByTagName('Fragments')[0].childNodes):

#only elements with name 'Fragment'

    if i.nodeName=='Fragment':

#"number of fragment" - from attribute 'Num'

        fragmentNum=i.getAttribute('Num')

#list in child node

        for j in i.getElementsByTagName('RPs')[0].childNodes:

            if j.nodeName=='RP':

                for u in j.childNodes:

                    if u.nodeName=='Times':

#choose attribute of the node

                        i1=j.getAttribute('Pgsz')
