    How would I go about reading info from a webpage and sorting it?

    Essentially a list of hiscores for a game.

    I want to get info from the hiscores list and sort it by using my own criteria for searching rather than the default one by the webpage.

    I have no idea how to start off, any tips?

    The webpage is:

    http://hiscore.runescape.com/hiscores.ws

    So as you can see, you can type user names to search or type a rank.

    How can I read this info into a database and then sort it, so I can apply my own search criteria?

    Thanks for any help.

    There maybe a bit of trouble opening the webpage because they just updated the main website and about 200,000 users are trying to re-update, lol.

    Usually just an array will suffice, sorted by score.

    To see if you make the table, compare the score with the lowest score on the table. If it's greater than that, then just find the correct place to insert into the array, then bump all the ones below down one place (and thus losing the former lowest score).
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Hi Salem,

    The thing is I know the C details of sorting. But how would I make a connection to a webpage to start reading in the info is the bit that is a mystery to me. Or is there another way to do it?

    I'll help you with it. I want to learn socket programming. Might be fun.

    It is a homework assignment?

    No it's not a homework assignment lol.

    It's a game. There are members, people who pay. And people who don't pay(me). But the same hiscores list applies to all people.

    Members are usually higher in rank, because they have more stuff to do. I want to sort the hiscores list into finding people who are not members only.

    Have been reading beej's guide to socket programming, it's too complex.

    libcurl may be a way to go, or wget perhaps?

    I didn't understand the implementation of things like AP_INET until I found out they are actually built in c modules, i found that out from other tutorials, i'm going to go over beej's again.

    libwww comes with a built in HTML/XML parser. But I'd suggest libcurl with something like libxml (or just parse the page yourself).

    Can you explain that in a bit more depth? ^^

    I downloaded libcurl, but I only got the source code, I have no idea how to compile so many different files.
