I need to have a parser that can parse ajax based web-sites as well as normal web-sites. For example flight result page at kayak.com . Input data for application: 1.) URL 2.) RegEx for the html to extract (or better way if you can suggest one) 3.) Type of return: text (of the resulting tag), html (whole tag) or attribute (of the tag) 4.) (optional) session variable Return from the parser: 1.) Url 2.) Data from the page (single or multiple, depending how many matches there were) 3.) Session variable: It needs to store a session somewhere, so that if needed, user can provide that session variable and app will restore all cookies and etc., so to imitate that it opens url from the previous session Parser needs to : 1.) Able to use proxy 2.) Run on a shared hosting (can use mySql if needed) 3.) Have some authentication 4.) Be able to support many parallel requests from different users 5.) Be fast Please respond with the price, your experience and proposal on how you will do it. Desired Skills: MySQL AJAX PHP Perl Keywords: Web Programming, AJAX, MySQL, PHP, Perl
