Subject: .include? for string

Hi,

I have an array a

=> [["abc", "def", "ghi|ghi|kl"], ["jkl", "mno", "ghi|pqr"], ["stu",
"vwx", "yz|abc"]]

Some strings contain the pipe character.

I want to delete all the arrows that do NOT contain a certain string.

I tried this:

a.delete_if { |x| !x.include? "ghi|ghi" }

=> []

Of course, the array I need would be
=> [["abc", "def", "ghi|ghi|kl"]]


I couldn't figure out a work around. Any wildcards available for string
checking in Ruby? Any ideas?
Thanks.

Cheers,
Chris
