A modification of that self-same little parser lives in penlight:

> pretty.dump(xml.basic_parse("<hello a='1'>bonzo</hello>"))
{
  "bonzo",
  attr = {
    a = "1"
  },
  tag = "hello"
}

This is the so-called LOM (Lua Object Model) format
(http://matthewwild.co.uk/projects/luaexpat/lom.html)

Incidentally, pl.xml was based on Prosody's stanza.lua

The nice thing about these styles of representation, of course, is
that looping from 1 to #t gives you the children.  (Note: I still
believe in #)
