 Example HTML Parser Application
 -------------------------------
 
-As a basic example, below is a very basic HTML parser that uses the
-:class:`HTMLParser` class to print out tags as they are encountered::
-
-   >>> from html.parser import HTMLParser
-   >>>
-   >>> class MyHTMLParser(HTMLParser):
-   ...     def handle_starttag(self, tag, attrs):
-   ...         print("Encountered a {} start tag".format(tag))
-   ...     def handle_endtag(self, tag):
-   ...         print("Encountered a {} end tag".format(tag))
-   ...
-   >>> page = """<html><h1>Title</h1><p>I'm a paragraph!</p></html>"""
-   >>>
-   >>> myparser = MyHTMLParser()
-   >>> myparser.feed(page)
-   Encountered a html start tag
-   Encountered a h1 start tag
-   Encountered a h1 end tag
-   Encountered a p start tag
-   Encountered a p end tag
-   Encountered a html end tag
