Sorry, I think you lost me there...
Aht do you mean by 'hashed array'? In Perl, a hash is a function from strings to scalars (a dictionary, a map, ...), an array is a function from integers to scalars (some call it a vector)
If you meant 'why is the order of the hash keys not preserved?', then the answer is: it's not supposed to. In a hash the order is not important, only the correspondance between keys (which can't be repeated) and their associated values is.
And for getting the values positionally, read the documentation for XML::Simple, there are various options to specify how to treat repeated elements.
