85732 PHP Online Sitemap Generator

Bidders must be familiar with the google/yahoo sitemap protocols. English speaking programmers only please. I am looking for a script that will perform the generation of xml/txt sitemaps in google/yahoo formats. The script must be able to 'fully spider' the external user submitted site whilst not using excessively using my server resources. The script must:- Accept a page being submitted as well as a domain name. The script must have a ‘crawl' progress meter. Have the resulting output available in total as a variable or array. It must also have the following user 'options':- Obey [login to view URL] file? Obey robots meta tags? Filtering of certain querystrings? eg sessionid, id, sess Options to pick up hrefs to other indexable files. eg pdf, xls, doc Start from a directory level deeper than the main domain and not spider upwards. The resulting output of the script must be able to be:- Edited online. Downloadable in both google(xml), ror(xml), yahoo(text) and html formats. Similar scripts and tips can be found at:- [login to view URL] [login to view URL] [login to view URL] Overall design is not important as I have a template to drop it into. Functionality and commenting of php code is a must please.
