What is the .net regex to find text between '$' and '<'?

Question

I want to find the regex pattern to find the text between a string and a char and replace spaces in the text with _.

Example. < Node Type="Text">Event Log < /Node >

Expected output : Event_Log

Thanks in advance. Please help.

To clarify Marco's comment: your example suggests all of the prefix $ should be included while the suffix < should be excluded. This doesn't match your requirements specification. Is this correct? — Daniel Renshaw, May 30 '12 at 07:29
You say "without $" but in expected output you have $$$ included...? — Hampus Brynolf, May 30 '12 at 07:30
we reject your desired output and put in it's place `Hello World` — Joe, May 30 '12 at 07:30
What is the desired output if the input is "... text $$$ Hello $ World "? Should that "internal" $ be treated as a boundary or as content? — Daniel Renshaw, May 30 '12 at 07:39

        string s = "here is my text $$$ Hello World </stop>";
        Match m = Regex.Match(s, "(\\$[^<]*)<");
        if (m.Success)
        {
            Console.WriteLine(m.Groups[1].Value);
        }

string str = "$$$ Hello World </stop>";
string sPattern = "[\\$]{3}([\\d\\s\\w]*)</stop>";

Match m = Regex.Match(str, sPattern, RegexOptions.IgnoreCase);

if (m.Success) {
    Console.WriteLine(m.Groups(1));
}

Converted from VB code and not tested after but should be ok.

Assuming the example is correct and the text of your question wrong, you need:

\$+[^$<]*(?=<)

If it's the other way around, try this:

(?<=\$+)[^$<]*<

BTW, all questions like this can be more easily answered using a tool like this online regex tester.
