last_non_null

Split the input on ASCII NUL ("\0") characters and returns the last non-null element in the resulting list.

Also see the line and oneline filters.

Example

[perl]
$Tag->filter({
op => 'last_non_null',
body => "One\0Two\0Three\0\0\0",
});
[/perl]

Results in:

Three

sub {
my @some = reverse split /\0+/, shift;

for(@some) {
return $_ if length $_;
}
return '';
}
