Use \xmltexentity

Already tried this. But doesn't work. I guess it has more to do with the definition of the entity in the stsrem. met vriendelijke groet, dr. Hans van der Meer Burgemeester Rijnderslaan 244 1185 MC Amstelveen tel. 020 6452701 / 06 53743629

After some experiments I am now fairly convinced that the entities are substituted BEFORE the typesettting actually starts. And thus changing the entity on the fly will have no effect. Is there a flag that can be set in order to delay the substitution until the actual moment of typesetting that part of the input? I examined files lxml-ent.lua and lxml-tex.lua but could not find how to this. dr. Hans van der Meer

I tried \directlua{xml.registerentity("DATE","NEWDATE")}

but neither does effect a change in the entity.

Why is that entry not set in the Lua-table entities? (file xml-ent.lua) has as that function:

function xml.registerentity(key,value) entities[key] = value if trace_entities then report_xml("registering entity %a as %a",key,value) end end

\def\DATE{THEDATE}\expanded{\xmlsetentity{DATE}{\DATE}}

\startxmlsetups typ:event

\def\DATE{NEWDATE}\expanded{\xmlsetentity{DATE}{\DATE}}

Using &DATE; within the <event>.

\stopxmlsetups

However, using &DATE; inside an <event> always results in THEDATE and never in NEWDATE.

How can I change the value of the entity inside the xmlsetups?
