Answer 5

Hi,

I've been working on a website about regular expressions that will address many frequently encountered tasks such as parsing numbers, IP addresses etc. The first three articles are done, and now I'm looking for some feedback.

Unfortunately this forum doesn't allow me to post links (yet), so here is the URL in disguise:

http://regex-for.com

Would be great if this was added to the link list.
