How can I use the python HTMLParser library to extract data from a specific div tag?

I am trying to get a value out of a HTML page using the python HTMLParser library. The value I want to get hold of is within this HTML element:

...
<div id="remository">20</div>
...

This is my HTMLParser class so far:

class LinksParser(HTMLParser.HTMLParser):
  def __init__(self):
    HTMLParser.HTMLParser.__init__(self)
    self.seen = {}

  def handle_starttag(self, tag, attributes):
    if tag != 'div': return
    for name, value in attributes:
    if name == 'id' and value == 'remository':
      #print value
      return

  def handle_data(self, data):
    print data

p = LinksParser()
f = urllib.urlopen("http://example.com/somepage.html")
html = f.read()
p.feed(html)
p.close()

I want the class functionality to get the value 20.

Little correction at Line 3

HTMLParser.HTMLParser.__init__(self)

it should be

HTMLParser.__init__(self)

The following worked for me though

import urllib2

from HTMLParser import HTMLParser

class MyHTMLParser(HTMLParser):

  def __init__(self):
    HTMLParser.__init__(self)
    self.recording = 0
    self.data = []
  def handle_starttag(self, tag, attrs):
    if tag == 'required_tag':
      for name, value in attrs:
        if name == 'somename' and value == 'somevale':
          print name, value
          print "Encountered the beginning of a %s tag" % tag
          self.recording = 1

  def handle_endtag(self, tag):
    if tag == 'required_tag':
      self.recording -=1
      print "Encountered the end of a %s tag" % tag

  def handle_data(self, data):
    if self.recording:
      self.data.append(data)

 p = MyHTMLParser()
 f = urllib2.urlopen('http://www.example.com')
 html = f.read()
 p.feed(html)
 print p.data
 p.close()
