How to wrap part of a text in a node with JavaScript

Question

I have a challenging problem to solve. I\'m working on a script which takes a regex as an input. This script then finds all matches for this regex in a document and wraps ea

As everyone has already said, this is more of an academic question since this shouldn't really be the way you do it. That being said, it seemed like fun so here's one approach.

EDIT: I think I got the gist of it now.

function myReplace(str) {
  myRegexp = /((^<[^>*]>)+|([^<>\.]*|(<[^\/>]*>[^<>\.]+<\/[^>]*>)+)*[^<>\.]*\.\s*|<[^>]*>|[^\.<>]+\.*\s*)/g; 
  arr = str.match(myRegexp);
  var out = "";
  for (i in arr) {
var node = arr[i];
if (node.indexOf("<")===0) out += node;
else out += ""+node+""; // Here is where you would run whichever 
                                     // regex you want to match by
  }
  document.write(out.replace(//g, ">")+"
");
  console.log(out);
}

myReplace('
This program is not stable yet. Do not use this in production yet.
');
myReplace('
This is a sentence. 
');
myReplace('
This is a another and more complex even super complex sentence.
');
myReplace('
This is a a sentence. Followed by another one.
');
myReplace('
This is a an even more complex sentence. 
');

/* Will output:
This program is not stable yet. Do not use this in production yet.
This is a sentence. 
This is a another and more complex even super complex sentence.
This is a a sentence. Followed by another one.
This is a an even more complex sentence.
