title: Is is possible that change HTML identifier tag in jsdom?
body: <p>I'm going to use jsdom as text data processing rather than as HTML. To distinguish between HTML and text data, I want to use custom HTML identifier tag, such as <code>{{tag}} {{/tag}}</code> instead of <code>&lt;tag&gt; &lt;/tag&gt;</code>. </p>
  
  <p>Following node jsdom example outputs <code>print("foo bar")</code> which is enclosed by HTML tag <code>&lt;python&gt;</code>. </p>
  
  <pre><code>html=`
  foo bar
  
  &lt;python&gt;
  print("foo bar")
  &lt;/python&gt;
  
  foo bar
  
  &lt;python&gt;print("foo bar")&lt;/python&gt;
  
  foo bar
  ` ; 
  
  const dom = new JSDOM(html);
  
  console.log(dom.window.document.querySelector("python").textContent); 
  </code></pre>
  
  <p>In this case, I want same result as above one from following one which uses custom HTML identifier tag not usual HTML identifier tag. </p>
  
  <pre><code>html=`
  foo bar
  
  {{python}}
  print("foo bar")
  {{/python}}
  
  foo bar
  
  {{python}}print("foo bar"){{/python}}
  
  foo bar
  ` ; 
  
  const dom = new JSDOM(html);
  
  console.log(dom.window.document.querySelector("python").textContent); 
  </code></pre>
  
  <p>Is it possible and if so How do I implement that? thanks.</p>
