I need to get all script tags from an html string, separated the inline

  • 0

I need to get all script tags from an html string, separated the inline scripts and the “linked” scripts. By inline scripts I mean script tags without the src attribute.

Here is how I get the “linked scripts”:

<script(.)+src=(.)+(/>|</script>)

so, having <script followed by one or more any character, followed by src=, followed by /> or </script>.

This works as expected.

Now I want to get all the script tags without the src tag, having some javascript code between <script .....> and </script>, but I can’t figure it out how to do that. I just started understanding regular expressions, so the help of a more experienced r.e. guru is needed 🙂

UPDATE
Ok, so dear downvoters. I have the html code for a whole html page in a variable. I want to extract script tags from it. How to do it, using jquery for example?

var dom = $(html);
console.log(html.find('script');

will not work. So, what is the way to accomplish that?

UPDATE 2
I don’t need to solve this problem with regex, but because now I am learning about them, I thought I will try it. I am opened for any other solution.

    Create a DOM element using document.createElement, then set its innerHTML to the contents of your HTML string. This will automatically parse your HTML using the browser’s built-in parser and fill your newly-created element with children.

    dummyDoc = document.createElement("html");
dummyDoc.innerHTML = "<body><script>alert('foo');</script></body>"; // or myInput.value
var dom = $(dummyDoc);
var scripts = dom.find('script');

    (I only use jQuery because you do so in your question. This is certainly also possible without jQuery.)
