Suggestions for finding tags

Hello,

I have an animation that is going to (I hope) pull in HTML content. What I envision is that we will have an HTML page (our code) and the swf will load it, look for specific tags, and assign them to various textfields based on what they are. For instance, a title tag will be assigned at the top of the swf, and image will be assigned off to the side and text will be placed to the other side.

How can I look for these specific tags with as3? Can all of these tags be in the same HTML file and seperated with as3?
