(Any Language) Common Regex

[minitech]

Everyone seems to be asking for these in the forum, so here are some common ones that will match anything valid.

E-mail:

^[a-zA-z0-9_\-\.]+@[a-zA-z0-9_\-\.]+?\.\w{2,4}$

URL:

^((http|ftp)s?://)?[a-zA-z0-9_\-\.]+?\.\w{2,3}(:\d{2,5})?(/[a-zA-z0-9_\-\.]*)*

Phone Number:

^(\d*(\-\s*)?)?((\(\d{3}\)\s*)|(\d{3}\s*(\-\s*)?))?\d{3}\s*(\-\s*)?\d{4}$

Image Source File (from HTML):

(?<=\<img\s.*?src=['"])[^"']+

IP Address with Optional Port Number:

(\d{1,3}\.){3}\d{1,3}(\:\d{1,5})?

New ones on request by PM or post.

An example of what the regex matches would be nice Email and possibly URL are obvious, but phone number isn't (not every part of the world uses the same phone number layout ).

[minitech]

Phone number matches Canadian & US phone number. I don't really know any other format, sorry! It will match anything like this:
12501234567 (Country code, area code, local phone #, no formatting.)
(250) 123-4567
250 123 4567
2501234567
123-4567
1-250-463-4448

etc. I tried to make the Regex so that they match all possible combinations for what they're used for.

minitech,
Im trying to scrape proxy ips from a web page
http://proxies.my-proxy.com/proxy-list-s1.html

what would be the solution for this.
Many thanks

[minitech]

That would be:

(\d{1,3}\.){3}\d{1,3}(\:\d{1,5})?

For IP address w/ optional port. *added*

Oh, and one for extracting MD5 hashes prefixed with MD5: :

(?<=MD5\:[^a-fA-F0-9]*)[a-fA-F0-9]+
