问题:

Using the Python Documentation I found the HTML parser but I have no idea which library to import to use it, how do I find this out (bearing in mind it doesn't say on the page).

回答1:

Try:

import HTMLParser

In Python 3.0, the HTMLParser module has been renamed to html.parser you can check about this here

Python 3.0

import html.parser

Python 2.2 and above

import HTMLParser

回答2:

You probably really want BeautifulSoup, check the link for an example.

But in any case

>>> import HTMLParser
>>> h = HTMLParser.HTMLParser()
>>> h.feed('<html></html>')
>>> h.get_starttag_text()
'<html>'
>>> h.close()

回答3:

I would recommend using Beautiful Soup module instead and it has good documentation.

回答4:

You may be interested in lxml. It is a separate package and has C components, but is the fastest. It has also very nice API, allowing you to easily list links in HTML documents, or list forms, sanitize HTML, and more. It also has capabilities to parse not well-formed HTML (it's configurable).

回答5:

You should also look at html5lib for Python as it tries to parse HTML in a way that very much resembles what web browsers do, especially when dealing with invalid HTML (which is more than 90% of today's web).

回答6:

I don't recommend BeautifulSoup if you want speed. lxml is much, much faster, and you can fall back in lxml's BS soupparser if the default parser doesn't work.

回答7:

For real world HTML processing I'd recommend BeautifulSoup. It is great and takes away much of the pain. Installation is easy.

回答8:

There's a link to an example on the bottom of (http://docs.python.org/2/library/htmlparser.html) , it just doesn't work with the original python or python3. It has to be python2 as it says on the top.
