AFAIR there is the attribute "index". If the value of index is numeric 
the resulting php array will be numeric entry, if not it will be a hash 
entry.

So this

<elements>
  <element index="a">III</element>
  <element index="b">IV</element>
  <element index="0">I</element>
  <element index="1">II</element>
</elements>

will become this

array( 'I', 'II', 'a'=>'III', 'b'=>IV');
