To use 
foreach $e (@{$data->{footnotes}})
{
print "$e->{footnote}{content}\n";
}

You'd need to specify KeyAttr => [].

With the default KeyAttr => [qw( name key id )], the above should be 

my $footnotes = $data->{footnotes}{footnote};
foreach my $id (keys %$footnotes) {
    print "$footnotes->{$id}{content}\n";
}

or 
my $footnotes = $data->{footnotes}{footnote};
foreach my $footnote (values %$footnotes) {
    print "$footnote->{content}\n";
}

Don't forget ForceArray => [qw( car footnote )]. XML::Simple is the hardest XML parser to use :(

By the way, if you used GroupTags => { footnotes => 'footnote' }, you could write ->{footnotes}{footnote} as just ->{footnotes}
