It is not in books24x7 where I have "free" access :)  Otherwise nothin'.

But as I was hunting for it in books24x7 I found this book:

Regular Expression Recipes: A Problem-Solution Approach

by Nathan A. Good
Apress © 2005 (320 pages)
ISBN:159059441X
This useful reference provides you with all the open source regular  
expressions you'll ever need, and explains how to use each one. This  
way, you can learn by example, rather than muddling through endless  
pages of syntax explanations.

that I will revisit in the coming days looks like.

Thanks anyway,
