One day, I was approached a couple of coder friends who were having a
friendly debate. "Frank, Mike here says that regex is an art. I say
it's a science. Break the tie".
"Neither", I replied, "It's witchcraft".
Yes, I'll be using this with a server side language. But I'm at a loss
as to how I'll actually implement it.
The notion is that I'll be "filtering" an entire body of html for the
relative links.
<a href="[/\.]*index\.cfm
guarantees the relative link (it'll always be called "index.cfm"). I
don't need to remember that. Then what I'm left with is, if it exists,
the query string to process. Sometimes regex gives me a case of tunnel
vision.
Thanks for the help, though. Regex is the sort of stuff that if you
don't have Mud Mind from a long days work, you'll get one. :)
