body: <p>I am trying to get the details of a person from <strong>MediaWiki</strong> in <strong>objective-c</strong>. I am using <a href="http://en.wikipedia.org/w/api.php?action=query&amp;prop=revisions&amp;rvprop=content&amp;rvsection=0&amp;titles=Albert_Einstein&amp;format=xml" rel="nofollow">http://en.wikipedia.org/w/api.php?action=query&amp;prop=revisions&amp;rvprop=content&amp;rvsection=0&amp;titles=Albert_Einstein&amp;format=xml</a></p>
  
  <p>I am getting the data in response as follow:</p>
  
  <pre><code>&lt;/i&gt;$0 = 0x07562e60 &lt;?xml version="1.0"?&gt;&lt;api&gt;&lt;query&gt;&lt;normalized&gt;&lt;n     from="Albert_Einstein" to="Albert Einstein" /&gt;&lt;/normalized&gt;&lt;pages&gt;&lt;page pageid="736" ns="0" title="Albert Einstein"&gt;&lt;revisions&gt;&lt;rev contentformat="text/x-wiki" contentmodel="wikitext"     xml:space="preserve"&gt;{{Redirect|Einstein}}
  {{Good article}}

  <p>now i want to get  the birthdate for the person in objective-c. somehow i can manage to get the birth_date also. But my question is, is any proper parsing is available for parsing these data?</p>
