In fact all you need is if( $parent_hex == 0 ) { blah } as the numeric comparison forces perl to convert the sv to a number and 0x00000 is correctly interpretted as 0 automagically. The problem with the if (! $parent_hex) {} example given is that without forcing numeric context perl sees the sting '0x0' which is not a null string '' and thus not false in this context.
