title: Reading Configuration xml files in C++
body: <p>How can the following configuration file be read in C++. Is there any support in STL. I can't afford to use other 3rd party libraries.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; 
  &lt;appSettings&gt;
      &lt;add key="FileType" value="doc"/&gt;  
      &lt;add key="FileLength" value="102234"/&gt;   
  &lt;/appSettings&gt;
  </code></pre>
  
  <p>I am not using managed C++. </p>
