Here how to find empty tag(name tag) using Node.js?

Answer 1

You have to traverse through all the relevant tags and check their content. If the content is found to be null then the tag is empty. Below is a piece of code to help you along the way.

  var emptytext=txtElement[0].childNodes[0];
  if(emptytext===null)
  {
     alert("Text is empty");
  }
