Extract script tags from a HTML string

Question

Or any other tags :)

for eg.

Answer 1

Define: outerHTML function (taken from here)

jQuery.fn.outerHTML = function(s) {
return (s) ? this.before(s).remove() : jQuery("<p>").append(this.eq(0).clone()).html();
}

Then assume your response is stored in data you can do:

$(data).filter("script").each( function(e) { 
    // do something with $(e).outerHTML()
} );

Answer 2

Use a regular expression with the pattern <script[^<]*</script>.

Answer 3

You can try something like:

 function getScriptsAsText() {
   var div = document.createElement('div');
   var scripts = [];
   var scriptNodes = document.getElementsByTagName('script');

   for (var i=0, iLen=scriptNodes.length; i<iLen; i++) {
     div.appendChild(scriptNodes[i].cloneNode(true));
     scripts.push(div.innerHTML);
     div.removeChild(div.firstChild);
   }
   return scripts;
 }

It returns a array of the current script elements as text, including their start and end tags.

You might also try outerHTML, but it's not that widely supported.
