XXX: Model Mismatch

• XML::XPath: attributes are objects

  • GetAttributes returns an array of attribute nodes
  • getName, getValue, getLocalName

• XML::Twig: attributes are stored in a hash

  • with accessors: $elt->att( 'foo')
  • but more commonly $elt->{atts}->{foo}
    • $elt->set_att( foo => $elt->att( 'foo')+1)
    • $elt->{atts}->{foo}++
