in thread Cropping the output of the pattern matcher

It seems as the delimiters were deleted, but the print is a little tricky

First, you had the string:
my $line = "a whole lotta shakin >pattern here< goin on";

and you did
my @bits_and_pieces = split /></, $line;

What did it make?
This code "splits" the string, searching '><' as delimiter. Because of '><' is not matched in the string, in @bits_and_pieces you will have only one element, and it would be
'a whole lotta shakin >pattern here< goin on'
(all the string)

In the other hand, you did this
my $line = "a whole lotta shakin ><pattern here>< goin on"; my @bits_and_pieces = split /></, $line;

Then, perl searches '><' in the string and splits it into an array.
So @bits_and_pieces would be now
('a whole lotta shakin ','pattern here',' goin on')

If you print @bits_and_pieces with
print @bits_and_pieces;
is printed
'a whole lotta shakin pattern here goin on'
as if the delimiters '><' where removed from the array.

Hope this help
