(Any Language) Common Regex

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

E-mail:

Code:

---

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

---

URL:

Code:

---

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

---

Phone Number:

Code:

---

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

---

Image Source File (from HTML):

Code:

---

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

---

IP Address with Optional Port Number:

Code:

---

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

---

New ones on request by PM or post. :)

Wow, nice post! I needed this! Thanks!

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 ;) ).

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.

Hi m8 ,

Can you give a quick sample on how to actually use this in a project/Form.

Thanks

Here's a demo project.

Thnaks alot minitech.

Update to e-mail address:

Code:

---

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

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

That would be:

Code:

---

(\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: :

Code:

---

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