function myFunction() {
  var str = document.getElementById("demo").innerHTML; 
  var res = str.replace(/&gt;/g, "%3E");
  document.getElementById("demo").innerHTML = res;

Thanks for the reply Ritesh Khandekar. I think your answer is definitely correct, but if I insert it into my notepad ++ where I code it doesn’t work .. I’m wrong somewhere. I write after the test. I don’t know why so many minuses on the question. 🙁

@maja, why are you expecting any DOM method to work inside notepad++? notepad++ is a text editor, not a browser. There is no DOM in notepad++ and therefore you shouldn’t expect web javascript scripts to magically work just because the contents of your file happens to be the source of a web page. However, if you open that file in a browser, the script will work correctly.

@maja I think you should take care of everything in Regex, even a space. And i think community want you to edit your question and be specific on one problem.
