Hi Gregory
A very useful note. I've put these comments up as a separate posting as there is no notification that I had put the comments on the document.

Document: Examples using Oracle Regular Expression Implementation

  
I don't know if you know it, but there is a bug in the implementation of regular expressions. I raised an SR about it several years ago but nothing came of it.
 
The problem is that if you use a string in more than one context, the context is ignored for the second and sunsequent use. It applies to all the functions, in 10G and 11gR1 (I haven't managed to test in 11gR2 yet).

Howdy, Stranger!
