Rasmus,

Thanks for your reply. With respect, this seems to be in a different  
class from matching strings with character position 0, IMO.

What about unsetting the iterator before foreach() looping begins? The  
iterator is altered anyway, so would this prevent it from being  
"attached" to previous foreach() iterations?

Best,
Richard
