Re^2: XML::Twig's twig_print_outside_roots adds extra blank lines to output

Thank you very much Remiah! That was exactly what I was looking for.

For those that come after, here is the final code I used to get my desired output:

#!/usr/bin/perl
use 5.016;
use strict;
use warnings;
use XML::Twig;

{
    open (my $OFILE, '>:utf8', './bits.xml') or die "Could not open [.
+/bits.xml]:\n$!\n$^E";
    
    
    ##
    ## An aproximation of 'twig_roots' and 'twig_print_outside_roots' 
+that
    ## keeps pretty printing and does not print superfluous blank line
+s
    ##
    my $t = XML::Twig->new(
        twig_handlers => {
            'statement'    => sub { _statement(@_, $OFILE); 1; },
            'statement//*' => sub { 1; }, # skip descendants of statem
+ent
            '_default_'    => sub { $_[0]->flush($OFILE); 1; }, # just
+ flush
        },
        
        pretty_print => 'indented',
    );
    
    $t->parse(*DATA);
    
    close $OFILE;
}

sub _statement {
    my ($_twig, $stmt_element, $OFILE) = @_;
    
    my $acct = $stmt_element->find_nodes('primary/acct', 0)->trimmed_t
+ext();
    
    if ( $acct eq '903264' ) {
        $_twig->flush($OFILE);
    } else {
        $_twig->purge();
    }
    
    return;
}
