Is it possible to search for keywords in an XML file?

Question

Hey all,
I'm currently searching for ways to count the number of pre-defined keywords in an XML file. An example would be trying to find how many times "war" is mentioned in a news networks RSS feed <title></title> and adding it to a variable.
I've found a few custom AS3 XML class files out there but nothing I've been able to adapt. I'm at the point of considering just taking the title of these news stories converting them all to strings and searching them that way...
I'd be grateful for any help
Thanks!

An XML element can have multiple attributes such as:
<title keyword="war" category="international">War Breaks Out in the Middle East!</title>
In the above example, the XML element <title> has 2 attributes named keyword and category.
So in my example I'm searching for the attribute named "keywords" within the element <newsItem>.
The XML document could be formatted something as the following:
============
<someNewsFeed>
     <items>
          <newsItem keyword="war" category="international" url="www.cnn.com/headline2010020111">War Breaks Out in the Middle East!</newsItem>
          <newsItem keyword="healthcare" category="politics" url="www.cnn.com/headline2010020321">Healthcare Bill Still Has Some Hurdles to Jump</newsItem>
          <newsItem keyword="lady gaga" category="entertainment" url="www.cnn.com/headline2010020981">Lady Gaga Has 360 Reach</newsItem>
     </items>
</someNewsFeed>
===========
So in my example, the if/else loop is looking through each XML node named <newsItem> and when it finds it, it then see if it has an attribute called "keyword" and if it does, it then looks to see if it contains the word "war". If it DOES, then it will do the proceeding actions.
===========
if (newsFeed.items.newsItem[q].attribute("keyword") == "war") {
          warKeywordCounter == warKeywordCounter+1; //increase your keyword counter
          trace("Current value of warKeywordCounter = "+ warKeywordCounter);
==========
I'm assuming you already know how to load external XML documents into flash.
I hope this helps.

Corrected if/else code to include right parentheses.
