Description |
I needed a regular expression to break urls into labled parts. This is what I came up with. Got a few ideas from regexlib.com and from this msdn article. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/script56/html/reconbackreferences.asp
http://www.domain.com/folder does return a match but will not grab the folder name unless there is "/" at the end.
http://www.domain.com/folder/

(?<Time>^(?:0?[1-9]:[0-5]|1(?=[012])\d:[0-5])\d(?:[ap]m)?)

Description |
A co-worker needed a regex to validate time. He could only find patterns that match a 24hour clock. I whipped this expression up to validate a 12hour clock. Hope somebody finds it useful.
