Regular Expression help

[Drakkon]

I am trying to replace text like this:

src="Lecture 1 Something About Something.rm"

to this:

src="Lecture_1_Something_About_Something.rm"

and so I've been trying textpad/notepad++/ultraedit and their regular expression feature but none seem to find based on what appears to me to be the valid regular expression:

\s+(?!([^'\"]*['\"][^'\"]*['\"])*[^'\"]*$)

Any help? ideas? better regular expression?

The problem with regular expressions and quotes is finding what is in quotes and what is not. So I'd suggest starting with searching for src=

Ultraedit has weird regular expressions. In ViM, I'd do:

s/\(src *= *"[^ "]*\) /\1_/g

repeatedly, until no more matches are found.

what language are you using for this? regex doesn't seem like the best solution for such a simple string manipulation

Most languages offer a method to do what you want. In C#, you'd use String.Replace(). In Java, you'd use String.replaceAll(). Technically you use a Regex as an argument in Java, but you can ignore that and just give it a string.
