Text retrieval problem

[Matthew Bentley <Matthew.bentley@xxxxxxxxxxxxxx>]

Hi there -
I have an element <act> which might contain the text "[1981] 2 NZLR 132"
Or it could contain: 2 NZLR 132
Or it could contain: [1981] 2 132

Essentially I want to grab the last number in the text sequence, the "132".
How can I do this?

Matt!
