Python – Parsing HTML using Python

html-parsingpythonxml-parsing

I'm looking for an HTML Parser module for Python that can help me get the tags in the form of Python lists/dictionaries/objects.

If I have a document of the form:

<html>
<head>Heading</head>
<body attr1='val1'>
    <div class='container'>
        <div id='class'>Something here</div>
        <div>Something else</div>
    </div>
</body>
</html>

then it should give me a way to access the nested tags via the name or id of the HTML tag so that I can basically ask it to get me the content/text in the div tag with class='container' contained within the body tag, or something similar.

If you've used Firefox's "Inspect element" feature (view HTML) you would know that it gives you all the tags in a nice nested manner like a tree.

I'd prefer a built-in module but that might be asking a little too much.


I went through a lot of questions on Stack Overflow and a few blogs on the internet and most of them suggest BeautifulSoup or lxml or HTMLParser but few of these detail the functionality and simply end as a debate over which one is faster/more efficent.

So that I can ask it to get me the content/text in the div tag with class='container' contained within the body tag, Or something similar.

try: 
    from BeautifulSoup import BeautifulSoup
except ImportError:
    from bs4 import BeautifulSoup
html = #the HTML code you've written above
parsed_html = BeautifulSoup(html)
print(parsed_html.body.find('div', attrs={'class':'container'}).text)

You don't need performance descriptions I guess - just read how BeautifulSoup works. Look at its official documentation.
