substitute a string in array

You can substitute in a scalar ($_) _before_ you split it into the array.
You substitute in a scalar with the s/// operator.

If you _did_ need to substitute in an array, you can do that with
the aliasing feature of the foreach loop:
# s/// as below
}
When you modify the loop control variable ($_ in this case),
the modification is made back in the array being foreach'd.
Read about foreach loops with:
perldoc perlsyn

If what you are really doing is escaping HTML entities, then
you should use a module that does that.
Assuming that you are NOT escaping entities and just want
to do a substitution:
s/ > / > /g;
will do it.

The s/// operator is documented on your very own hard disk:
perldoc perlop
and the regular expressions that the operator uses are described here:
perldoc perlre
