Screenscraping Job in php

Hi I need to extract some information from an existing website. The webpage HTML displays products. 1. I would like to extract the urls of the products. 2. and then go to individual product details page from the url that you have extracted in step 1 and extract product photo , product name and description. I have had a look at the html of the page and its all nicely formatted so using the php dom explorer/ parser would be relatively easy job for someone who has done it before. Thanks
