Question

I need to grab inline script tags inside html pages.
The regex will eventually be driven from c#.
Now I am using Expresso for test purpose.

The following is the best for now:

.*<script.*\r\n(.*\r\n)*\s*</script>

i.e.

• .*<script catch the script tag
• .*\r\n catch anything till the end of line
• (.*\r\n)* catch other lines of the script
• \s*</script> catch the closing script, with any indentation before

It grabs ALL the stuff between the first tag, inculding html and other script tags.

Answer 1

Two scripts on the same line will break your regex. Try it on the source of the page with your question.

Parsing HTML with regex is not a very good idea (there is a link in the comment to your question which answers why the <center> cannot hold); use HTML parser instead.

The next code snippet selects the <script> nodes by using HtmlAgilityPack:

var doc = new HtmlDocument();
doc.Load(html);
var scripts = doc.DocumentNode.SelectNodes("//script");

Isn’t this is simplier than regex?
