OK, one more try:
$t->{'top'}{testcode} = sub {
my ($node, $t) = @_;
$t->{pre} = "A List\n\n";
my $pos = 1;
foreach my $kid ($node->findnodes('./node()')) {
if ($kid->isElementNode && $kid->getName eq 'sub') {
$t->{pre} .= "$pos) ";
$pos++;
}
$t->{pre} .= apply_templates($kid);
}
return DO_SELF_ONLY;
}
