RSS html rip

Hi

I want to make an RSS feed.  What I want it to do is first log into a site, get values from a specific HTML page, and then put these values into the feed.  Using PHP, Perl, Ruby or Java, does anyone know a way that I can fetch a HTML page from an external web site (remembering that it will need to provide some authentication first)?

Specifically what I'm looking for is a way to fetch a page behind authentication automatically, using my username and password for the site, and to basically save that page to my server so that I can work on pulling out the values I want.

also, it could use any unix/linux program such as wget as this could be set as this could be activated from within the coded solution.

wget can do it...
   
   wget --help

you'll see it can do HTTP authentication, and also cookie loading - so you'd need to find your cookie placed by the site at log in.

I tried that... I pointed wget at the location of the cookie and it didn't work! (the site doesn't use HTTP authentication)

Maybe there's a different way? programmatically?

using cookies has nothing to do with HTTP auth.

Try this, forcing wget to use the cookie you want. Specify cookies off and then the cookie name and value (see: http://www.delorie.com/gnu/docs/wget/wget_9.html).  

Example: wget --cookies=off --header="Cookie: LOGIN=username:passwordhash" http://www.yoursite.com

where password hash is either a plain text password or the hashed password in your cookie.

Result! Using php shell_exec I can get this to fetch my page (well, not my page but that page I want). Cheers.
