body: <p>I have HTML.</p>
  
  <pre><code>&lt;body&gt;
      &lt;span&gt;
          &lt;font="color"&gt;

            ORDER_NUMBER:
          &lt;/font&gt;
      &lt;/span&gt;
      &lt;span&gt;M123456JK98766&lt;/span&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>M123456JK98766 is 14 digit number. Need to check only 14 digit character.</p>
  
  <p>I like to find a order number M123456JK98766 from HTML. How can I retrieve that? that number can be changed every time by using page refresh.</p>
  
  <p>I have no option to add id against M123456JK98766.</p>
