I emerged xxe conglomerate kile etc. Xxe is a excellent tool for edit docbook file, with so much convenience. Kile is the corresponding tool for latex. Conglomerate is not so good.
Docbook and latex are all good things, but they all support Chinese very poor.
I gave away the idea of use these things in my formal official document. but I still want to study them and use them in my routine work and study. I still can't decide which one to use, docbook or latex.
