Hans, thanks a lot, the explanation makes sense, but your suggestion is
not yet clear enough for me: how would I then process the node?
context(lookuptable[mytype]["mytype"])
gives again the serialized xml.
\startluacode
local lookuptable = { }
function xml.functions.lookup(t)
local mytype = xml.text(t, "c")
local myvalue = lookuptable[mytype]
if not myvalue then
myvalue = xml.first(t, "d")
lookuptable[mytype] = myvalue
context("registered: ")
else
context("reused: ")
end
-- each found node gets an id
lxml.flush(lxml.id(myvalue))
context(" or ")
-- in tex mode a to-tex serializer is the default
xml.cprint(myvalue)
end
\stopluacode
One place to look for tricks is in x-mathml.mkiv / lua (I know, I should
finish that manual).
Hans
