Fighting with regex….

I’m using this to find pieces of HTML-string between certain elements:

 for (i = 0; i < 2; i += 1) {
   target = block[i];   // like BODY or HEAD
   regex = RegExp('<' + target + '>(.)+</' + target + '>');
   // in case string passed includes breaks/spaces
   data = data.replace(/(\r\n|\n|\r)/gm,"").replace(/\s+/g," ")
             .match(regex);
   entry = data[0].replace(/<!-- [\s\S]*? -->/g, '');
   console.log(entry);
 }

While this works fine, it returns something like this:

<head>....everthing I want ....</head>

Question:
How do I need to modifiy the regex, so that I can still specifiy the element whose content I need, but which returns only the content and not content & tokens (like <head></head>).

Thanks!

    Use the first matching group instead of the whole match.

    regex = RegExp('<' + target + '>(.+)</' + target + '>');

    and then…

    entry = data[1].replace(/<!-- [\s\S]*? -->/g, '');
