in reply to htmltreexpather.pl - xpath helper, creates xpath search strings from html

off-by-one error (OBOE)

Dag nabbit, there was an off-by-one error (OBOE); apparently, xpath starts counting at 1 (confirmed with xpather, xpath-checker), not 0, so change all occurances of 
my $count = 0;

to 
my $count = 1;
