How do you produce a regex that matches only valid URI. The description for URIs can be found here: http://en.wikipedia.org/wiki/URI_scheme. It doesn't need to extract any parts, just test if a URI is valid.
(preferred format is .Net RegularExpression) (.Net Version 1.1)
- Doesn't neet to check for a known protocol, just a valid one.
Current Solution:
^([a-zA-Z0-9+.-]+):(//([a-zA-Z0-9-._~!$&'()*+,;=:]*)@)?([a-zA-Z0-9-._~!$&'()*+,;=]+)(:(\d*))?(/?[a-zA-Z0-9-._~!$&'()*+,;=:/]+)?(\?[a-zA-Z0-9-._~!$&'()*+,;=:/?@]+)?(#[a-zA-Z0-9-._~!$&'()*+,;=:/?@]+)?$(:(\d*))?(/?[a-zA-Z0-9-._~!$&'()*+,;=:/]+)?(?[a-zA-Z0-9-._~!$&'()*+,;=:/?@]+)?(#[a-zA-Z0-9-._~!$&'()*+,;=:/?@]+)?$
