Extract file name from URL

If you have a predictable URL, i.e. the same amount of '/' characters you could do multiple Find() and Right() methods to strip out the text.  Otherwise you could build a web service that parses and returns string data and hook up to an IPC event or possible pass in parameters via URL.

This should match on the filename out of an arbirtrary URL.  Also takes into account any arguments passed beyond that in the URL and strips em out (ex:  http://www.somesite.com/folder/file.docx&someargument=nothingwecareabout

This REQUIRES http:// or https:// to be in the string to work, as something.com can look like a filename.  You could modify it to be more specific if that's in your requirements by having it skip anything ending in .com/.net/.co.uk

(w+)(.w+)+(?!.*(w+)(.w+)+)

@s0m3one Yeah, you're right.  A simple web method with Request.Uri.AbsolutePath will do it. [WebMethod] public string StringParse(string inputString) {      return Path.GetFileName(new Uri(inputString).AbsolutePath); }

You would use one of the inline functions dealing with regexp. Documentation is here:  http://help.k2.com/onlinehelp/k2blackpearl/userguide/current/webframe.html#Regular_Expressions.html

Again, it depends really how/where you need to perform this logic, but, if it's in one of the places where inline functions are available you should be good to go.  Note that I did not heavily test that regular expression, so you may find an edge case or two that breaks it.

I'd also suspect that .NET uses a regular expression to figure out where the last "/" character is in the URL in the web service approach, which is also workable, and may be useful in areas where an inline function cannot be used.
