Re: Deleting specific element in array in FOREACH loop

Grep is god's gift to this situation. Check out grep. Basically, you can write a subroutine that takes the array element as an input and returns true or false, true if it should be included.

Then you write a version of @newarray=grep {&subroutine($_)} @oldarray. The new array will only contain the elements that the subroutine returned true for.
