#!/usr/bin/env python
#-----------------------------------------------------------------------------
# This example will read an XML file and parse out the data using the
# xml.etree.ElementTree library that is included in the standard library.
#
# There are two methods for doing XML parsing, the DOM method loads the XML
# file into a tree structure in memory and the SAX method reads the XML file
# as a stream of text. The DOM method is fast but only works on small files
# that will fit in memory. The SAX method can work on arbitrary length files.
#
# I will be using Python's ElementTree module in the example below because I
# want to use the tools in the standard library. You can get more information
# about ElementTree at:
# http://docs.python.org/library/xml.etree.elementtree.html, and
# http://effbot.org/zone/element.htm
#
# There are a number of external XML parsing libraries that can be used with
# Python. Details are available at wiki.python.org/moin/PythonXml. If you plan
# to do a lot of XML processing, then I would suggest looking at the lxml
# library. It is based on libxml2 and libxslt and is fast and easy to use. You
# can get more information about lxml at http://lxml.de/index.html.
#-----------------------------------------------------------------------------

# Import any needed libraries below
#-----------------------------------------------------------------------------
# We need the ElementTree module
import xml.etree.ElementTree
#-----------------------------------------------------------------------------
# Place any necessary functions below this.

def print_movie(movie, year):
print "The movie \"%s\" was released in %s.\n" % (movie, year)

# Begin the main program.

# Load an XML file into the tree and get the root element.
xml = xml.etree.ElementTree.ElementTree(file='movies.xml')
root = xml.getroot()
# Get a list of all the movie elements in the file.
movies = root.findall('movie')
# Parse the movie element to get the "id" attribute, the title element and the
# released element.
for movie in movies:
# Get the value of the "id" attribute
id = movie.attrib['id']
print "Parsing movie #" + id
# Get the text inside the first "title" tag. Returns None if the "title"
# tag is not found. Returns an empty string is returned if the tag was
# found but no text was found in the tag.
