Your expression works fine Richard, as does '(^| )ho', but can you tell me why '[ ^]ho' doesn't work?
With ^ you means an anchor, but within the brackets it's a simple char.

Err no, it inverts the test. [^ ] means any character *except* a space.

Have a nice day,
Hi Marijn, Andreas,

I think Andreas is right, note the ordering of characters in the above example as [ ^] rather than [^ ]. So if the '^' is taken as literal '^', can I check for the beginning of a string in the brackets, or am I forced to use the (^| ) syntax?

Is it just me or are regular expressions crazy?
