The $tree - is it an array? a scalar? a variable?
ref can answer that for you: 
print ref($tree), "\n";

outputs: 

ARRAY

Or, if you read the free manual (XML::Parser), it says: 

For elements, the content is an array reference.

Or, looking at the Dumper output: 

$VAR1 = [
          'list',
          [
            {
              'name' => 'name list'
            },
            0,
            '
        ',

the square bracket signifies an array ref.

how do I get access to it?

perlreftut is a good place to begin figuring out how to access Perl data structures such as this.
