title: NSXMLParser with multiple attributes
body: <p>I have the following XML (doing an app for iPhone):</p>
  
  <pre><code>&lt;Row&gt;
  &lt;Field name="employee_id_disp"&gt;00070431&lt;/Field&gt;
  &lt;Field name="given_name"&gt;John&lt;/Field&gt;
  &lt;Field name="family_name"&gt;Doe&lt;/Field&gt;
  &lt;/Row&gt; ...
  </code></pre>
  
  <p>How can I retrieve values only for one of the attributes, for example value "John" for attribute name="given_name" ?</p>
  
  <p>Thanks for answers.</p>
