[NTG-context] letters in context mkiv

25 Jul 2017

      Dear Contex’ers,

I use Context for many things. One of them is letters.
I have used the letter module of mkii with an xml database (see example), but now I would like to step forward to mkiv.

I have found out how to process the xml data from an xml file (now in the buffer). The recipient’s address neatly shows up in the designed place. (See pdf). So far, everything seems OK. 

Yet when I add text, only the text appears, and all address data from the xml file disappear.

You can try it out by uncommenting the %\input knuth or %tekst lines.

I have tried various options, but for now I have no idea how to proceed further.

Context Version: 2017.07.17 00:20
Lua 5.2.4, This is LuaTeX, Version 1.05.0.

Your help is much appreciated!

Kind regards,

Robert

%toname is not used in setupletter because toaddress contains all data.
%kix is used for adding a barcode to the address.
