I was looking for something similar and found out that adding a third argument to the xml.collected reverses the iterations. Looks like the argument has to be true in a boolean sense, so puting any "string" there will do the trick. for v in xml.collected(doc, "/chapter/section", "string") do ... end Jano ___ 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://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

Tried this: local relationTable = xml.all(viewFromXML,"/connection") for i=#relationTable, 1, -1 do connectionFromXML = relationTable[i] parseXMLConnection( rootFromXML, connectionFromXML, viewFromXML, rootFromOverrideXML) end but it fails as well.
