Added change to allow xml elements that are strings to be represented in...

Normally xml data that is string like 
\<public_ip_addresses\>
      \<public_ip_address\>247.240.138.128\</public_ip_address\>
\</public_ip_addresses\>
is parsed as "public_ip_addresses"=>"247.240.138.128"
This change allow it to be represented as an array to match json
"public_ip_addresses"=>["247.240.138.128"]
