how to do this in wordpress, or php?

hi, dont want you to spoonfeed me, just some directions if you shall.


i want to automatically pull html content to my site from a list of links, but omitting some of the html input for example i have on amazon .com

<title>
<img>
<desc>
<price>

and all the other html stuff. I only want to pull
<title>
<img>
<price>



i think i should do this with regex. are there any plugins for wp, or is there a good script for this for php?
