This method is called to process arbitrary data (e.g. text nodes and the content of <script>...</script> and <style>...</style>).
The data argument is the text content of HTML. 
from HTMLParser import HTMLParser

class MyHTMLParser(HTMLParser):
    def handle_data(self, data):
        print "Data     :", data
