deleting strings from an array

[mrjcfreak]

I have an array, some of whose values are words, some of whose values are just whitespace. What is the best way for 3 lines of code to delete altogether the values which contain just whitespace?

I am willing and eager to use reg exp's.

@yourArray = grep /[^\s+]/, @yourArray;

Thanks very much... and just one more question...
If I am using a foreach loop, is there a way of using an elements position in an array; e.g.

foreach (@myArray) {
print qq~$_ is in the $nth position in this array~;
}

replacing $nth with the position number.

@myArray = ("apple","banana","carrot");
foreach (@myArray) {
print qq~$_ is in the $nth position in this array\n~;
}

would print:
apple is in the 0 position in ths array
banana is in the 1 position in this array
carrot is in the 2 position int this array

You could use a counter:

my $count = 0; 
foreach (@myArray) { 
 print "$_ is in the " . $count++ . " position in this array\n"; 
}
