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.rub...

Cheers,

Pedro.

Nice. I've done this sort of thing, but much more 'manually' than you
show here.

I'm sure y'all know this, but just as a reminder...

The proper procedure is to go 1, 2, 5, 3.

You can skip straight from 1 to 3 if you have no immediate access to 2.
But making an honest attempt to achieve 2 is highly recommended.

Hitting 3 immediately following either step 2 or 4 is usually
counter-productive.

Failure to hit 3, however, is a death sentence to any ambition you may
have to get the story published. Whenever I am tempted to skip step 3
(which is frequently) I remind myself of that fact.

You're allowed to go back to 5 only after arriving at 4 (editorial
feedback)... or running out of editors to try in an attempt to hit 4.
