Found a pretty sweet solution here: http://blog.ostermiller.org/find-comment
Excerpt:
Now we just need to modify the comment end to allow any number of *:
/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/
We now have a regular expression that we can paste into text editors that support regular expressions. Finding our comments is a matter of pressing the find button. You might be able to simplify this expression somewhat for your particular editor. For example, in some regular expression implementations, [^] assumes the [\r\n] and all the [\r\n] can be removed from the expression.
This is easy to augment so that it will also find // style comments:
(/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/)|(//.*)
Be sure to read the caveats, however, as this will remove comments from with comments, or can uncomment commented code improperly. Worked perfectly for me, however :-)
