Title	Test Details URL Validator
Expression	^(http(?:s)?\:\/\/[a-zA-Z0-9]+(?:(?:\.|\-)[a-zA-Z0-9]+)+(?:\:\d+)?(?:\/[\w\-]+)*(?:\/?|\/\w+\.[a-zA-Z]{2,4}(?:\?[\w]+\=[\w\-]+)?)?(?:\&[\w]+\=[\w\-]+)*)$
Description	A simple but powerful URL validating regex. Accepts multiple sub-domains and sub-directories. Even accept query strings. Now accept ports! Accepts HTTP or HTTPS. Also accepts optional "/" on end of address.
Matches	http://website.com | http://subdomain.web-site.com/cgi-bin/perl.cgi?key1=value1&key2=value2

Title	Test Details Email Validator
Expression	^([a-zA-Z0-9]+(?:[.-]?[a-zA-Z0-9]+)*@[a-zA-Z0-9]+(?:[.-]?[a-zA-Z0-9]+)*\.[a-zA-Z]{2,7})$
Description	After reading RFC2822 (then taking two asprin) I've come to the conclusion that I will not allow all RFC compliant email addresses to be entered in the forms on my website and will never have an issue with it. I demand a stricter tolerance for my website than RFC allows. If you're like me and only want to allow 99% of those email addresses entered into web-forms then use this little gem of an email checking regex. Also, I've never met anyone who would submit an email address taking full advantage of RFC2822's allowances nor would I care to accommodate one who would.
Matches	[email protected]
Non-Matches	[email protected]

Title	Test Details Absolute Path
Expression	^((?:\/[a-zA-Z0-9]+(?:_[a-zA-Z0-9]+)*(?:\-[a-zA-Z0-9]+)*)+)$
Description	An overly simple UNIX based path regex. The path must begin with a forward slash. The path segments may not lead or end with an underscore or dash which is a good thing. They also can not be doubled (__ or --). Another good thing. I've omitted all the punctuation that RFC allows until further notice.

Description	After reading RFC2396 and researching it a little more I put together this regex to use for verifying a path rather than my non-compliant, safer, overly simple one. More specifically an absolute path.
Matches	All RFC2396 compliant paths
Non-Matches	A non-RFC2396 compliant path

Description	This is my simple phone number regex. There are many like it but this is mine. It accepts the most common United States phone number formats that normal people use.
