Subject: Beginners question about Array#assoc

Hi, I am new to Ruby and still finding it very strange even though I am
enjoying learning it immensely.

I have this code:

if an_array.assoc(tag_name) == nil
 ...

and of course it doesn't work because I either get an array back or a
nil object.  It makes it very difficult to have a simple if statement
like the above that can handle both eventualities.  I don't need the
array returned, I just need to check to see if the element exists to
take a certain action.


What is the Ruby way of doing this?

Thanks,

Chad.
