Regular Expression Replace

[crazyboybert]

Hi

I want to write a regex to replace the _ character in framework generated control ids. Easy except I need the expression to match all instances of an _ except where it is the first character in the string. Can't work it out at all.

Obviously ^_ will match the first character if it is an underscore but how do I match all underscores in a string except if one is the first character?

Thanks

Try
\b_. to match _A but not A_

Rob,
Did you get this working. If not can you post a couple of before and after test strings.

Yeah was being stoopid Using the framework Regex classes you can perform a replace starting from the specified position in the string thus something like

regex.Replace(string, replacement, -1, 1)

would replace all instances starting from the character in position 1 (the second in the string)...

Im sure there is someway using look ahead style stuff to write a regex which matches all instances of a charcter except if its in position 0 in the string, but i couldn't find it
