I am not very experienced with perl and hashes. I was looking for some help with displaying values from a SOAP request that returns XLM. I have used the XMLin function to parse the XML, but I don't understand the syntax to display individual elements, and perhaps to list them all. I can see the data that I want in the structure using dumper. (some output included below) Thanks for your help:

#!/usr/bin/perl 
#use strict; 
use LWP::UserAgent;  
use XML::Simple; 
use XML::Parser; 
use Data::Dumper; 

# this is the RPC call:  
$xml_file = '<?xml version="1.0" encoding="UTF-8"?>
