body: <p>How do I write the OR keyword in XML?</p>
  
  <p>For example, how do I write this line in XML?</p>
  
  <pre><code>#if (define A &amp;amp;&amp;amp; define B) || (define C &amp;amp;&amp;amp; !define D)
  </code></pre>
  
  <p>I am only able to find these: <code>&amp;lt;</code> for <code>&lt;</code> less than, <code>&amp;gt;</code> for <code>&gt;</code> greater than, <code>&amp;amp;</code> for <code>&amp;</code> ampersand, <code>&amp;apos;</code> for <code>'</code> apostrophe, <code>&amp;quot;</code> for <code>"</code> quotation mark. How should I change <code>||</code> OR?</p>
