Replacing mulitple matches between 2 strings using regex

Question

I want to do a Regex.Replace() to get rid of all the \r\n between the ul and /ul tags. Now I love writing RegEx as much as the next guy, But I can't for the life of me figure out the correct pattern to use. Any one have any idea what the pattern I need to match all instances of /r/n between the two tags using RegEx?

This is a note&nbsp;I am using to display bullets&nbsp;here are some examples\r\n<ul>\r\n<li>somethign</li>\r\n<li>somthing else</li>\r\n</ul>

Does the string contain newlines, or does it literally contain the string `\r\n`? — Welbog, Jul 13 '16 at 20:45

There's probably a way to accomplish this is a pure regular expression, but one option is to use a regex and a custom match evaluator:

value = Regex.Replace(value, "<ul>.*?</ul>", (match) =>
    {
        return match.Value.Replace("\r\n", "");
    }, RegexOptions.Singleline);

And as a side point: Once you start thinking about parsing HTML fragments, you should consider using HtmlAgilityPack. It's not always necessary, but it can save trouble as you get more and more complex requirements.

I like your style. I tried something similar to this but it seems the singleline option is key. Thanks my friend, you made my life easier — JSON, Jul 13 '16 at 21:02
