My xmlcodec project will do this but you'll need to write some simple
classes to do it. For this case, something like:

class PeopleFormat < XMLElement
  xmlformat 'People Format'
end

class People < PeopleFormat
  elname :people
  xmlsubel_mult :person
end

class Person < PeopleFormat
  elname :person
  xmlattr :name
  xmlattr :size
end

With this you can do:

people = PeopleFormat.import_xml_text(myXMLTextOrFile)
people.person.each {|p| ...}
people.person.first.name
people.person[2].type

You can find it at http://xmlcodec.rubyforge.org

Cheers,

Pedro.
