Re: Accessing "external" tables from within LuaExpat callbacks

[Michael Bauroth <Michael.Bauroth@...>]

First of all thank you for your sample. Unfortunately the script
produces the same error. Only if I replace

stuff[#stuff+1]= attr

with

table.insert( stuff, #stuff + 1, attr )

the program works. The disadvantage of this: I can only use array based 
table, because table.insert( stuff, name, attr ) isn't allowed and

stuff[ name ] = attr

produces the same error as before.

Regards
Micha
