News Aggregators
<p>I need to create a news aggregator for our application, something similar to reading AP News from Yahoo, or something like <a href="http://popurls.com/" rel="nofollow">http://popurls.com/</a>; the problem is that I don't know how it works. <br />
So, a couple of questions: <br />
1) How do I determine what news site to aggregate? Do I hard-code the specific site's url into the application? <br />
2) How do I know the url of the specific news? It's one thing to know the site name, but another to know the url of the specific news. <br />
3) How do I embed the news content onto our application? <br />
4) How do I determine (without specifically hard-coding everytime) the category(ies) each news should go? 
<br />
<br /> 
Thank you very much for the help.</p>
