Here is a trivial example using LuaExpat:
\starttext
\startluacode
require "lxp";
text = '<p>hello world</p>'
callbacks = { EndElement = false,
StartElement = false,
Default = function (p, s) tex.sprint(s) end }
p = lxp.new(callbacks)
\stopluacode
Some xml output: \directlua{p:parse(text)}!.
\directlua{p:close()}
\stoptext

Wonderful! Thanks Taco. Just for the record, for other Windows users,
to get this working I downloaded
luaexpat-1.1.win32-lua51.zip
from http://luaforge.net/projects/luaexpat/files
and from that I copied the following DLLs
(from luaexpat-1.1.win32-lua51.zip)
libexpat.dll
lxp.dll
into the following directory on my PC
C:\Context\tex\texmf-mswin\bin\lib\lua
(adapt to your ConText install)
One question, in the minimal example below, the XML text:
text = '<elem1> text <elem2/> more text </elem1>'
parses fine *if* on a single line. If I break the text onto multiple
lines, eg
text = '<elem1> text <elem2/>
more text </elem1>'
it fails with
! LuaTeX error <main ctx instance>:3: unfinished string near ''<elem1>
text <elem2/>'.
} = lxp.new(callbacks)d
\dodostartluacode ...d \directlua \zerocount {#1}}
l.21 \stopluacode
Why is this --- is this a catcode issue?
Can you suggest a fix?
Once again, thank you, as always, for sharing your expertise.
Warm wishes
Graham

end,
CharacterData = function (p, s)
tex.sprint(s)
end
