Newbie needs help w/ XML, PHP, and HTML

[thejaykob]

Ok, so here are my two questions.  BTW, I have already spent a good amount of time scouring the Internet for answers...  As broad as my question may be, I can almost 100% guarantee you I have read every tutorial already.  Yet I cannot make this work. 

 

1.)  I have a website at tirademedia.com.  On my website are various articles (http://tirademedia.com/ft20091025.html, ft20091217.html, et cetera.  What I want is a PHP-based way to extract local content from a centralized location, rather than using a clunky HTML file for each article.  I realize I will first have to centralize my various articles.

 

2.)  If you go to the website breitbart.com, you will see breaking news stories (from an external site).  Clicking on any of them gives you an PHP-based article that IS readable by a web-crawler.  Using PHP, how do I extract external XML data in a similar fashion, and display its content as an article (readable by a web-crawler)?  The XML file I will be working with is http://hosted.ap.org/lineups/TOPHEADS.rss?SITE=AZPHG&SECTION=HOME

 

I am not asking for someone to program this for me--but I would appreciate more than simply a link to a web tutorial that is several years old.
