Dan,

Doing it in SQL is the better way anyway. What I needed to learn first 
in Valentina was the need to destroy cursers before creating a new one. 
Everything is done with an open curser in Valentina SQL. Now this is 
going back to early in 1999 when I spent a few days learning Valentina 
& SQL. I was searching for a fast parser when I discovered the 
TextCruncher Xtra for Director. I had spent a lot of time on their list 
talking with the inventor of Valentina about getting a fast parser 
added. Once I had found what I was looking for I created an example 
that worked in tandem with the Director example that comes with 
Valentina. This was the first PNLP example tested and created and it 
was used to parse XML in order to pull-parse the XML and selectively 
populate the Valentina database using an SQL curser. Once I had what I 
was looking for I didn't do much more with the database. There is still 
a link to the source code that can be read with a text editor or 
Director at their website.

Follow the PNLP link to the bottom where I still keep a link to the 
original example. MTML 3.0 will be out in the next few months. Because 
of Revolution it will be in the easiest to use format/GUI and the most 
powerful, feature rich, version yet. So much for Vapor-ware 
announcements ...
