title: Get HTML source code as a string
body: <p>I want the source code of an HTML page (<code>1.html</code>) to be used in another page (<code>2.html</code>). Furthermore, I want to perform operations on it in <code>2.html</code>.</p>
  
  <p>Is there a way to do this? </p>
  
  <p>EDIT: <code>1.html</code> is a separate public webpage and I do not have access to make changes to its source code. I have to do whatever I need only by using <code>2.html</code>.</p>
