[flexcoders] E4X equivalent to SQL where 'like %' expression ?

[pbrendanc]

I'd like to extract the list of emps from the following XML where name
starts with 'Jo' (returns Jones, Johnson). In SQL I can use the
expression 'where name like 'Jo%'.

Anyone have examples of how this be done via an E4X expression 
(I could not find any examples of this in the docs).

TIA,
Patrick
