Subject: a newbie question

Hi,

I am trying to create an array from another array using a regular 
expression to compare them. If an element match the regular expression, 
then I want it to appears in my new array, otherwise it can be 
discarded. I have come up with the following code (for example, getting 
strings than end in 'abba' in an array of string)

new_array = (array.collect { |x| if( x =~ /abba$/ ) then x else nil end 
}).compact

It works fine, but I want to know if there's is a more simple way to do 
this since I do this a lot in my scripts.

Thankx,
Ben.
