I've just finished a major enhancement to our cross-platform 
report-writer so it can write a document out to XML and retrieve it.

The single desktop document contains one or many reports, each containing
- schema
- style
- layout
- data

I enhanced our expatpp wrapper for expat so it supports invoking 
nested parsers. This is a really easy way to parse data within a very 
strict domain, much like your serialisation demands. It means you can 
keep the parser for a given object self-contained to avoid any given 
parser becoming complex. It also means the string comparisons as the 
events arrive are much more optimal.

You can grab expatpp from 
http://www.highway1.com.au/adsoftware/expatpp.html including sample 
code showing how the report writer parsing works.

More information on the report-writer and links to our (now) free 
OOFILE database API including the XML output and data parsing at
