I put this question up a while back (around July 2003), my solution, 
which I have been using in some poduction enviroments, was to handle it 
like the following:

<TEST foo="Hello" bar="world">Some <B color="Blue">Text</B></TEST>

...becomes...

xml = {
   tag = "TEST",
   att = {
      foo="Hello",
      bar="World"
   }
   [1] = "Some",
   [2] = {
      tag = "B",
      att = {
         color = "Blue"
      }
      [1] = "Text"
   }
}

It's then a pretty simple case of parsing the ipairs of the table to get 
the sub-nodes/text whilst having a fixed place for the node names and 
attributes.

So far I haven't had any problems with this arrangment and have some 
basic lua functions to work with the structures, which I want to post up 
on the wiki, once I've given the boss a going over with the open source 
clue hammer :)
