Tired of giving a output to XML::Writer? Me too. This allows to do

    use 5.10.0;

    use XML::Writer::SelfContained;

    my $doc = XML::Writer::SelfContained->new;

    $doc->startTag('doc');

    $doc->characters("Howdie");

    $doc->dataElement( stuff => "Mooh" );

    $doc->endTag;

    say $doc;

use strict;
use warnings;

use base 'XML::Writer';

use overload '""' => \&to_string;

sub new {
    my $output;
    my $self = XML::Writer->new( OUTPUT => \$output, @_ );
    $self->{output_stream} = \$output;
    return bless $self, 'XML::Writer::SelfContained';
};

sub to_string {
    my $self = shift;

    $self->end;
    return ${$self->{output_stream}};
}

WWW::BambooHR::XMLWriter ?

I don't have much XML simple experience, but this does look simple to use.
