Have a look at the specifications for a URI, especially the Syntax components.
I am trying validate an input from a text box and I want to make sure it is a well formed Share Point address, e.g.
Does anyone have a regular expression that can do this or another method of validating the input address?
You can constrain the input format by defining patterns that the input must match.
Hello, I have this regex "/^([a-z0-9_-] \.)*[a-z0-9_-] (\.[a-z])$/" to validate website addresses of the form com, xyz.com, us com, xyz.com, us Hello, I have this regex "/^([a-z0-9_-] \.)*[a-z0-9_-] (\.[a-z])$/" to validate website addresses of the form com, xyz.com, us com, xyz.com, us How does any of that really validate anything. |[0-1][0-9][0-9]|[0-4][0-9]|[0-5])\.)([0-9][0-9]? |[0-1][0-9][0-9]|[0-4][0-9]|[0-5]))$/i; for you?
As it is now, your only validating the (type of characters, length of characters) which doesn't do anything that your wanting to truly do!

For instance in your profile on SO :) In most cases you don't have to check if a string is a valid address.
:,.;]*[-A-Z0-9 [email protected]#/%=~_|]' //URL: Replace URLs with HTML links preg_replace('\b(https? It's quite easy to check if the given url starts with [protocol]:// and add if it doesn't.
This How To shows how you can use regular expressions within ASP. Regular expressions are a good way to validate text fields such as names, addresses, phone numbers, and other user information.
