    # storing the contents in 
    # "file" object Put in the 
    # path of your XML file in

    # nodeName returns the type of 
    # the file(in our case it returns
    # document)
    print( file.nodeName )

    # firstChild.tagName returns the 
    # name of the first tag.Here it 
    # is "note"

    firstname = file.getElementsByTagName( "fname" )

    # printing the first name

    lastname = file.getElementsByTagName( "lname" )

    # printing the last name
    print( "Surname: " + lastname[ 0 ].firstChild.nodeValue )

    favgame = file.getElementsByTagName( "favgame" )

    # printing the favourite game
    print( "Favourite Game: " + favgame[ 0 ].firstChild.nodeValue )

    # attributes(Here tag "player"
    # has "name" attribute)
