I think what you want to use here is the NoAttr option of XML::Simple. This inhibits the generated XML to contain attributes and all hash key/values will be represented as nested elements instead.

use warnings;
use strict;
use XML::Simple;

my $hash = {
    name => 'bob',
    value1 => 'blah',
    value2 => 'blah2',
};


my $xs = new XML::Simple;
my $xml = $xs->XMLout($hash,
                      NoAttr => 1,
                      RootName=>'newPhone',
                     );

print $xml;
__END__
<newPhone>
  <name>bob</name>
  <value1>blah</value1>
  <value2>blah2</value2>
</newPhone>

The sad truth is that XML::Simple options can somewhat paradoxically get really convoluted, but is is really useful for tasks of similar kind...
