Ok guys, I need to build a script that connects to a websites, grabs and  
opens a link, parses the contents in that link and submit the findings  
in a form, I have most of it done, But the link for the file i need to  
parse is random and changes on every session so i always get an error  
when i am trying to open it… It looks something like this:

site = Net::HTTP.post\_form(url,  
{‘start’ =\> ‘1’})  
link = site.body.scan(/href="(.+?)"\>/)  
open(link) # it fails here, because its not the same session

Any ideas? Sorry if i didn’t explain myself very well

tia
