title: XML Entity not defined in Chrome
body: <p>My browser is telling me:</p>
  
  <pre><code>error on line 2 at column 308899: Entity 'ntilde' not defined
  </code></pre>
  
  <p>and the specific line is in my xml as:</p>
  
  <pre><code>&lt;LastName&gt;Trevi&amp;ntilde;o&lt;/LastName&gt;
  </code></pre>
  
  <p>the name was originally <code>Treviño</code>, but it was modified via php's <code>htmlentities</code> function.</p>
  
  <p>What can I do to get php and xml to play nicely?</p>
