I'm still digesting and playing with Massi's reply; will probably be 
back with more questions :-)

Anyway:

If you've filtered something out like this

local tree = xml.filter (t, "../chapter[@title='mytitle'")

you can then apply a command to it

lxml.command(lxml.id(tree), ".", "xml:chapter:command")

and have to define the command as

\startxmlsetups xml:chapter:command
	\xmltext {#1} {content}
\stopxmlsetups

for example.
