[Tutor] HTML Parsing

Hi, I want to write a little script that parses an apache mod_status page. I want it to return simple the number of page requests a second and the number of connections. It seems this is very complicated... I can do it in a shell one-liner: curl 10.1.2.201/server-status 2>&1 | grep -i request |

As usual there are a number of ways. But I basically see two steps here: 1.) capture all dt elements. If you want to stick with the standard library, htmllib would be the module. Else you can use e.g. BeautifulSoup or something comparable. 2.) Check all dt contents either via regex, or with a .s

Re: [Tutor] HTML Parsing

Just from memory, you need to subclass the HTMLParser class, and provide start_dt and end_dt methods, plus one to capture the text inbetween. Read the docs on htmllib (www.python.org | Documentation | module docs), and see if you can manage if not, come back with questions ;) Andreas Am Montag,

[Tutor] Why next vs. __next__ ?

Is there a reason why generators have a special method named "next" vs. "__next__"? All other Python's special names have the double underscore prefix/suffix. http://docs.python.org/ref/specialnames.html Are there other special names like "next" that don't have the double underscore delimiters?

It's actually considered a mistake. The original rationale is spelled out in PEP 234 - see the Resolved Issues section: http://www.python.org/dev/peps/pep-0234/ It is being renamed to __next__() in Python 3.0 and there will be a builtin next() method that calls it. Instead of iterator.next()
