title: Parsing xml in NSXMLParser
body: <p>I have read many examples of how to get text out of xml files, but just don't get how to.  Here is a sample xml file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;questions&gt;
      &lt;set&gt;
          &lt;question&gt;Question&lt;/question&gt;
          &lt;answer&gt;Answer&lt;/answer&gt;
      &lt;/set&gt;
  &lt;/questions&gt;
  </code></pre>
  
  <p>Using <code>-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI</code>, what's the easiest way to get the values <code>Question</code> and <code>Answer</code>?  I already have my parser delegate hooked up and all that blah.</p>
