 Posted: Mon Sep 13, 2010 3:48 pm Post subject: Parsing an html table |
 |
|
There's this table (all but the first in that page) which I find very useful but hard to use. Its purpose is to know HOW to get an item, while what i want to know is WHAT you can do with a given item.
Being lazy, I thought I could programmatically parse it and get all the data, so i could even display it in some more user-friendly view, for example:
| Code: | [Fire]-,
V
[Fire]-->[Fira]-->[Firaga]
^
[Fira]-'
|
But it'll take something like AGES to write it in C++. So I remembered the good old days in which I knew perl: maybe some basic file i/o and a hash could do, but I'm very flexible and i like learning so anything is fine.
So, in your opinion, what's the best/fastest way to do this? (Can be broken down in two steps: parsing the original table to xml or a database or some programming-friendly thing, and data->user, that is, the program that will read the data and do stuff with it)
EDIT: found another one here (CTRL-F for "[COL:CM]", table is nearly at the end of the page) which may be easier to parse as it's in ascii.

Any modern programming language, including C++, has tools for parsing. For C++, I'd probably use Boost::Spirit, since it's what I know best. For Perl/Python/Ruby/etc I'd probably just scrape crap with regexps, starting w/ /.*?(\<table class=\"wiki.*?\<\/table\>)/m all the while knowing that the proper way would be to use a more correct, although verbose, library like mechanize or hpricot or something.

| Any parser combinator should be able to handle this nicely (Boost.Spirit, Parsec, FParsec, etc).
