Sorry about the confusion, this is a snippet from a larger xml structure, I should have included more XML for the example. Try the following code instead:

#!/usr/bin/perl
use XML::Simple;
use Data::Dumper;

my $xml = qq|<?xml version="1.0" standalone="no"?>
<!DOCTYPE document SYSTEM "whocares.dtd">
<document>
    <QuestionList>
        <Question>
            <Id>3</Id>
            <Text>Are dingos your friend?</Text>
            <Answer>Satisfactory</Answer>
        </Question>
        <Question>
            <Id>3</Id>
            <Text>Should I have hit preview a second time?</Text>
            <Answer>Yes</Answer>
        </Question>
    </QuestionList>
    <QuestionList>
        <Question>
            <Id>11</Id>
            <Text>Should this run out of memory?</Text>
            <Answer>No</Answer>
        </Question>
    </QuestionList>
</document>|;

my $xml_ref = XMLin($xml);

print Dumper $xml_ref;
print $xml_ref->{'QuestionList'}->{'Question'}->[0]->{'Answer'};

in the full code I check to see if this is a list of questions or not... But if you try that one out Question indeed is an array ref as my print would suggest.
