Question

I’ve got a lot of html response code, at some part there’s this part:

</td>
</tr>
    <input id="hiddenloginurl" type="hidden" name="loginurl" value="/sensor.htm?id=10240">
</table>

How can I parse the html code and get this id with python? The problem is, at every new api call, the id is changed.

BeautifulSoup

Beautiful Soup provides a few simple methods and Pythonic idioms for navigating, searching, and modifying a parse tree: a toolkit for
dissecting a document and extracting what you need. It doesn’t take
much code to write an application

Beautiful Soup automatically converts incoming documents to Unicode
and outgoing documents to UTF-8. You don’t have to think about
encodings, unless the document doesn’t specify an encoding and
Beautiful Soup can’t autodetect one. Then you just have to specify the
original encoding.

Beautiful Soup sits on top of popular Python parsers like lxml and
html5lib, allowing you to try out different parsing strategies or
trade speed for flexibility.
