All, Thanks to Thomas's help, I've been making my way up the learning curve.
My TEI xml has empty lb elements indicating lines in the original and corresponding lb elements in the translation. I'd like to be able to set these numbers in the margin so that readers may coordinate the lineation. So far I have this: \startxmlsetups xml:lb \lineNumbers{\xmlatt{#1}{n}} \xmlflush{#1} \stopxmlsetups \defineinmargin [lineNumbers] [outer] [normal] which works, but I'd like to be able to set only every fifth or tenth line number. Is there a way to perform some arithmetic on the value of the n attribute and then execute \lineNumbers accordingly? for example: if n%5 == 0 then \lineNumbers else ignore <lb> Thanks, Jon ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
