title: simplexml_load_string() StartTag: invalid element name
body: <p>I use simplexml_load_string() to parse a XML API response.</p>
  
  <pre><code>$lien = "http://myresponseurl";
  $page = simplexml_load_string($this-&gt;get_data($lien));
  </code></pre>
  
  <p>Everythink is working good, except in this case:</p>
  
  <pre><code>&lt;libdivision&gt;&lt;1500 Poule H&lt;/libdivision&gt;
  </code></pre>
  
  <p>Where the text to get back should be "&lt;1500 Poule H" but, the "&lt;" caractère is also in XML the symbol of an opening tag...</p>
  
  <p>What should I do to get back "&lt;1500 Poule H" without any errors ?</p>
  
  <pre><code>Warning: simplexml_load_string(): Entity: line 4: parser error : StartTag: invalid element name
  Warning: simplexml_load_string(): &lt;libdivision&gt;&lt;1500 Poule G&lt;/libdivision&gt;
  Warning: simplexml_load_string(): ^

  <p>Thanks for help</p>
