Hello Friends,
I am using Python 3.3.3 on Windows 7. I would like to know what is the
best method to do HTML parsing? For example, I want to connect to
www.yahoo.com <http://www.yahoo.com> and get all the tags and their values.
The standard library contains a parser module:
html.parser
Which can do what you want, although its a non-trivial exercise.
Basically you define event handler functions for each type of
parser event. In your case you need handlers for starttag and
data, and maybe, endtag.
Within start-tag you can read the attributes to determine the
tag type so it typically looks like
def handle_starttag(self, name, attributes):
if name == 'p':
# process paragraph tag
elif name == 'tr':
# process table row
etc...
However, you might find it easier to use BeautifulSoup which is a
third-party package you need to download. Soup tends to handle
badly formed HTML better than the standard parser and works by
reading the whole HTML document into a tree like structure which
you can access, search or traverse...
