Hello Guys I am trying to use TWIG module to delete some nodes in a file and print in a new file . It's 2Go bytes files so I tried to parse my XML chunk by chunk but it seems the method that I am using is not working because my file XML is corrupted at the end it's because of the flush which is not reading all the file

Here the code

 

#---------------------------------------------------------------------
+---------
# This function is to add a twig handler to remove the node in paramet
+er
#---------------------------------------------------------------------
+---------
sub delete_node {
#---------------------------------------------------------------------
+---------
    my ($node_to_delete,$file_to_read) = @_;
    
    copy($file_to_read,$file_to_read.'-tmp_'.$dateLog.'.xml')
    
    open my $file_end, '>', $file_to_read.'-parsed_'.$dateLog.'.xml'
    my $handlers = {$node_to_delete => section_delete_node($file_end)}
+;
        my $twig = new XML::Twig(pretty_print => 'indented',
                            twig_handlers => $handlers,)->parsefile($f
+ile_to_read);
    close $file_end;
    
    if (-s $file_to_read.'-parsed_'.$dateLog.'.xml') {
        move($file_to_read.'-parsed_'.$dateLog.'.xml', $file_to_read);
    }
    else {
        move($file_to_read.'-tmp_'.$dateLog.'.xml', $file_to_read);
    }
}

#---------------------------------------------------------------------
+---------
# This function remove the node in parameter
#---------------------------------------------------------------------
+---------
sub section_delete_node { 
    my ($file_end)= @_;
    
    return sub {
        my( $t, $section)= @_;
        $section->delete();
        $t -> flush($file_end);
    }
}

<?xml version="1.0" encoding="UTF-8"?>
    <record category="B" editor="" entered="2000-12-04" sub-category="

        <person ssn="" e-i="E">
            <title xsi:nil="true"/>
            <position xsi:nil="true"/>
            <names>

                <age xsi:nil="true"/>
                <as_of_date xsi:nil="true"/>
                <dob xsi:nil="true"/>
                <dobs>
                    <dob xsi:nil="true"/>
                </dobs>
                <deceased xsi:nil="true"/>
            </agedata>
        </person>
        <details>
            <id_numbers>
                <id loc="INT" type="">fd</id>
            </id_numbers>
            <place_of_birth xsi:nil="true"/>
            <locations>
                <location country="df" city="re" state="">Shahrara</lo
+cation>
