title: What is the use of &amp; in XML?
body: <p>In my XML, I found something like this: </p>
  
  <pre><code>&lt;str_pair key="1" value="&amp;amp;1 Orange" /&gt;
  </code></pre>
  
  <p>I'm just curious what is the use for <code>&amp;amp;</code>? </p>
  
  <p>Also, when I bind the whole value(<code>&amp;amp;1 Orange</code>) to a WPF menu and I run the windows application, the menu will show the whole value included the <code>&amp;amp;</code>.</p>
  
  <p>If I run the compiled/published app, will the <code>&amp;amp;</code> disappeared from the menu?</p>
