Ah, I understand better now. Yes, it's true that HTML
Help is picky about file extensions. I did not realize that the files had to
have the XHTML extension.
I did a little experimenting, and I am able to
get files with this extension to work in HTML Help, but unfortunately
it breaks easily if file associations are altered in Windows. Here's what I did
to make it work:
(1) Gave a topic file the extension ".htm.xhtml". This
is a workaround to an HTML Help issue that prevents it from searching topic
files that use an extension that does not start with the letter
H.
(2) Made sure that the XHTML document does *not* have
an XML prolog (<?xml...?>). HTML Help only treats the document as an HTML
document if this prolog is missing; otherwise it will be treated like
XML.
This works in a default Windows installation. However,
when I install another browser (Firefox) as the default browser, the XHTML
extension gets taken over, and the CHM behavior reverts to trying to open the
file externally. Even going back and trying to re-map the extension or to set IE
back as the default browser doesn't fix the problem from that
point.
I suppose all this doesn't help if you can't solve the
final problem, but maybe you'll see a way through it that I haven't. I'll keep
chewing on it as well.

Re: Docbook with Math ML/Latex => PDF

Your input got me further. Thanks.
You are right - the HHC uses IE but there are a
few things that got in the way.
1. It appears that the only way to have IE &
FF actually display the MathML is to make sure it's <xml:output>
is "xml"
AND html.ext must be set to ".xhtml". That
was the only way that I could make the MathML show up in a browser. (Bob
mentions this in his book)
2. HHC only knows HTML. [now I'm stuck] It
will allow me to use an XHTML file, but thinks its a foreign file and try to
load it in a browser. I'm using the 4.74 version of the HTML Help
compiler.
3. Looking at the HTMLHELP stylesheets, it looks
like it calls the html style sheets.
Anybody have comments on this setup? I
suspect that because of namespaces the MathML needs a well behaved XML - like
XHTML.

An
other thing that I have to deal with is multiple outputs: PDF, html,
MSHelp.
With PDF jeuclid works fine. With html FFor IE7 can be
dictated.
However, MSHelp is uninteligent and doesn't handle MathML.
Does anyone have a solution for that? I don't really want to create
a
process that converts the MathML to image. That would be my last
resort.

I'm a little confused by this.
HTML Help uses Internet Explorer to
display the HTML pages, so just
about anything that can be displayed in
IE should also be displayed in
HTML Help topics.
I'm not familiar with JEuclid, from its
SourceForge page it looks like
it's a Java applet? Perhaps the problem
is merely getting the Help
topics to point to the right location to load
the applet. This can be a
little tricky with files that are compiled
into a CHM, but it's usually
doable.
