I'd revert the tests. First see whether it's empty, then whether it
equals something:
if (!defined $item or $item eq $tempitem) {
do something

I guess the capital "I"s were introduced by your mail client (I know
some programs think they know better:-}
Anyway the
$1 eq !$tempitem
doesn't really make sense.
If you want to say "$1 does not equal to $tempitem" it should be
either
$1 ne $tempitem
or
!($1 eq $tempitem)
or
not ($1 eq $tempitem)
In your version you first LOGICALY negate the $tempitem (which means
that if $tempitem is 0, 0.0, "0", "" or undef you get 1, in all other
cases you get an undef. And then you compare the 1 or undef with the
$1. Not likely to be what you meant.

This is even more crazy :-)
