Help with Regular Expressions

[digitalv]

I'm familiar with using a Regular Expression to replace text within a string, but I'm trying to figure out how to use it to replace text BETWEEN two strings.

Anyone have any ideas how to do this?

I want to replace everything between:

<!-- BEGIN -->

and

<!-- END -->

string ResultString = null;

ResultString = Regex.Replace(SubjectString, "(<!-- BEGIN -->)([\\s\\S]+)(<!-- END -->)", "$1Replacement text here$3");
