Fwd: Useful syntax highlighting (font lock) in a mixed xml lua file

[Timur Aydin <ta@taydin.org>]

Hello and a happy new year to everyone!

I had sent the following post to the help-gnu-emacs group, but thinking
that it might require some special lisp programming, wanted to post the
same question here as well...

Hi,

I am working on an xml file that has an embedded CDATA section which
contains lua source code. I am mostly working on the lua code and would
like that code to be syntax highlighted by emacs. When I activate
lua-mode, it understandably gets confused because of all the surrounding
xml. When I activate xml-mode, the xml stuff is properly syntax
highlighted, but the lua code in the CDATA section is uniformly colored
plain text.

Is there a way to utilize font-lock mode in a sensible manner? I
attempted to put the lua code in a separate file (script.lua) and then
included it into the xml using DOCTYPE and ENTITY tags, but this didn't
help, because I don't have any control over the software that parses
this xml file. It isn't able to deal with extra xml tags.

So my only hope is to be able to tell emacs to font-lock a region
bounded by a CDATA tag using lua-mode and to font-lock the rest using
xml-mode. Is there a way to do this?
