I was looking for something like this recently. In particular, I need

Which is completely wrong. It's fixable but at present it is an
example of a shortcoming in the design.
My particular need is to fabricate XML out of thin air rather than
read and modify a source document. How would you recommend I do so in
order to preserve the well-formedness of the Lua table?
Presently my code provides no constructors for new nodes, the likes
of makepi() are there to deconstruct the input string into a table.
The problem is that I am so used to OO programing that getting my
head around how to do things without OO is difficult. I keep thinking
"all we need is an add method", but the tables are not objects. Of
course I just need to get my head around Lua OO and I will have that
