Add support for regular expressions

[polmonroig]

I think it would be interesting to add support for regular expressions. It looks like it already supports email/ip parsing so it doesn't look like a complex feature.

Nice work by the way!

Thanks so much, @polmonroig for your comment and feedback.
Sure I will look at how can I support regex ( if possible regex find and replace as well )
