Hi Thomas, Thanks for your advice. I would like to have a system with which I can send letters to people in my database. It would be nice to be able to make selections according to labels (probably with xmlatt), but that can be done later. I am not a programmer - when I read the documentation, I do not understand enough of it to the extent to port it to a new program, but I can adapt and try existing code. Thusfar I have been trying to use the letter module with the xmltext and xmlflush commands. What can be done to make this work? Thanks!

I still cannot generate letters from my xml database

So what are you missing? Make a complete minimal example (you can pack the xml part into a buffer and then use \xmlprocessbuffer), then people will try to help you. Right now, we can't even guess where your problems lie. And writing "I'm not a programmer, so I can't read documentation" is not very motivating - you've been told where to begin, and you appear to be making some progress, so show us what you have.
