Thanks. I've tried adding the no warnings 'recursion'; to both the example script above and to the real script (there in the smallest lexical scope available). It does not suppress the warnings in either case.
I wonder if there would be a way to simply collect and not print the warnings, perhaps with an eval. However, the attempt below still prints the same warnings as the original example script above.
#!/usr/bin/perl
use HTML::TreeBuilder::XPath -weak;
use strict;
use warnings;
my $ent = HTML::TreeBuilder::XPath->new;
$ent->parse_file(\*DATA);
eval {
no warnings 'recursion';
$ent->delete;
};
if ($@) {
print "FOO\n";
}
exit(0);
__DATA__
<html>
<head>
<title>foo bar</title>
