Parsing HTTP pages

atomicfire

I'm quite new to PHP programming, though I have worked with several scripts in the past, mainly PHPnuke (modifying it to enhance features, close bugs...)

A new project i'm working on requires the script to get a web page, parse the response, and spit out only relevent information back to the browser. I really have no idea how to implement it, or what to call the proccess so here is a flow diagram to hopefully get the gist across:

User inputs UPC to script
Script does a search on Amazon.com, gets result page that shows one hit
Script follows link to the page with one hit
Script parses page, returns useful data to user (Item name, price, user comments...etc)

Thank you very much for your help!

The script will only extract information from a specific layout, Amazon's product page. The script will be searching audio CD's and I will need to pull artist information, track list, year of release, and record label. Thanks for the reply!

EDIT::
Example page where I will need to extract information from:
