Re: Regex for URL (John Baughman)

[B. Perkins]

John,

Since QFree uses PCRE (Perl Compatible Regular Expressions) you will
find many pattern examples via Google, e.g. "PCRE URL regex". It is
worth looking at a few of these to understand some of the challenges
that URL matching can present. It really depends on how you define a
"URL" and how strict you want to get. For example, must the top-level
domain match allowed values (.com, .net, etc.)?

Best,

Brad

        Before posting to the NUG, I spent hours browsing the internet  
looking for something that would work reasonably well without much luck.

        Thanks John, that is a great site and had several URL Validation  
expressions to choose from plus a whole lot more.
