RegEx Question: No stingy matching?
Hans,
Thanks for clarifying that. Is JScript 5.5 the same as I.E. 5.5?
I use I.E. 5.5 and Netscape 4.75 and one of them (don't remember which one)
was not implementing this construct. For now, I've switched to a more
traditional (in JavaScript anyway) use of indexOf() and substring() methods
to do the same work.
Thanks again Hans. Take care now.
-John
