processing lua table in xml...

processing lua table in xml...

[Thomas A. Schmitz]

Dear all,

I had asked a similar question some time ago and had received a reply 
from Hans (http://article.gmane.org/gmane.comp.tex.context/81049), but 
the method there doesn't work in this case. Working example difficult, 
hence code snippets, I'm afraid.

I process file A.xml. I pull in stuff from file B.xml and store the 
result as a lua table:

for e in xml.collected(xml.load('B.xml'), 'a') do
    for d in xml.collected(lxml.id(e), 'b') do
       local sortword = xml.attribute(b, "/", "xml:id", "0")
       local entryword = xml.text(b, "entry")
       local translation = xml.first(b, "translation")
       mytable[sortword] = { }
       mytable[sortword]["ew"] = entryword
       mytable[sortword]["tr"] = translation
    end
end

so the table contains the xml. The "translation" part contains further 
nested xml elements. Later, when processing A.xml, I want to retrieve 
this stored xml and have it processed:

local checkword = xml.text(t, "c")
local translation = mytable[checkword]["tr"]

but whatever I try:

lxml.flush(lxml.id(translation))

or

xml.cprint(voktable[myword]["tr"])

or

xml.cprint(translation)

I always get the serialized xml typeset, but not processed. So: how can 
I get context to process the xml that is stored in the table?

All best

Thomas

hard to say without an example but there is probably no setup associated 
to what you flush so does lxml.command (id, pattern, setup) work i.e. 
force a setup to be applied?
