Forum:Using woots xml page

From Woot Wiki

[edit] Introduction

THIS IS A PROOF OF CONCEPT ONLY IF YOU USE THIS SCRIPT FOR A LIVE CHECKER YOU WILL UNDOUBTEDLY GET BANNED BECAUSE THERE IS NO CACHING INVOLVED WITH THIS

Please see Forum:Woot_dev_offers_some_guidance for information.

I quickly made a script that shows how to access the data in that page. You can use this as a base to plug into your particular implementation of the cache.

Awesome. Wouldnt just copying the file lcoally, then having JS read it for AJAX save the server some load :) letting the end user browser do the parsing, opposed to the server do it saves the webhost. Check out the google code forums, we've been discussing that for awhile--ikishk 19:58, 1 February 2007 (UTC)

[edit] The Code

<?php
/**
 * wootxml.php
 * 
 * DO NOT CALL THIS FILE DIRECTLY WITH EACH REQUEST, IT WILL ALWAYS HIT WOOT'S SERVERS
 * REMOVING THE PURPOSE OF A CACHE TO BEGIN WITH.  THIS IS PROOF OF CONCEPT CODE ONLY.
 * 
 * It could also be used instead of the code to query woot.com AFTER you have ensured 
 * the cache has expired
 *
 * I didn't parse the individual products section.  Only advantage to that would be the
 * product description being a little more detailed and could be plugged into a search
 * form.
 *
 * I also could not figure out how to detect the bouncing "almost gone" link.  It seemed
 * to kick in once the sold value went about .90, not sure if that's what determines it
 * (this has been confirmed as how the "almost gone" link works, by 90% sold)
 *
 * THIS IS RELEASED INTO THE PUBLIC DOMAIN.  YOU MAY USE THIS SCRIPT FOR ANY PURPOSE
 * WITH OR WITHOUT GIVING CREDIT
 * 
 * *updated to work with new xml format woot is using.  Basically woot's special values
 * have "woot:" prefixed.  If it ever changes, looking at the $wootdata array will show
 * the new values
