Обсуждение: Array iterator

Hi,

Is there any way to apply a built-in function to all elements of an 
array (and get an array as result) without using a procedural language?

Specifically, I'm looking at being able to take a string, tokenise it 
into an array and apply soundex to each of the tokens (not particularly 
efficient or effective, but serves this specific purpose).  Have got as 
far as:

select regexp_split_to_array('string with tokens', '[^A-Za-z0-9]');

Can one now process the resulting array in a single shot within SQL 
itself?

Regards,

maybe
select regexp_split_to_table('string with tokens', '[^A-Za-z0-9]');
would help?

That did the job, thanks!
