Hiya folks, I am trying to make use of the Modello framework to build
a very simple xml parser which can parse out a tree-like node
structure, kinda like this:
---8<----
<layout>
<name>default</name>
<nodes>
<node>
<name>testing</name>
</node>
<group>
<name>testing</name>
</group>
</nodes>
</layout>
--->8---
Where the .mdo defines the Layout class as taking * Node instances by
interface and Group implements Node and extends from NodeSupport.
Node is defined externally in the src/main/java tree... since
<interfaces>... usage seems to spin around here:

....

I've alos defined a NodeSupport class which defines that name field
to a String and implements Node too. So what I'd like is for modello
to generate a parser which will recognize "node" and make a new
NodeSupport() and recognize "group" and make a new Group() and then
go about its normal processing fluff.
I've been hacking at this for like hours now... keep thinking I've
gotten it working, but alas it seems to be futile. :-(
Anyone know if Modello can be configured to even to this?
I'd really like to use Modello, cause it spits out tiny parsers that
do the job well (er if the input is correct and I'm not hitting a
limitation that is).
Anyways... I've given it my shot... and now I've gotta ask for some
help adivse.
Anyone got clue how to make it work?
