Try the "parse_string" method instead. The documentation says that XMLin

"parse_string" explicitly expects an XML string. So there's no logic to

Perl expects the data to have a value for every key. The first error - odd
number of elements - means that Perl saw a key without a corresponding
value. The data has an odd number of elements. To save into a hash, it

and" keeps returning decimal numbers
between 3 and 4, like 3.4526180 and 3.9876261 and 3.1182304.
Instead of picking answers at random, what about shuffling the answers and
take the top 5? They're still in a random order. And you eliminate even the
possibility of an infinite loop. A modu
value, which
is what the warning tells you.
Perl expects program variables to start with a letter or underscore. So
"$a999" or "$num" work like you expected.
