[oXygen-user] How to include smaller files into a "master document" in Oxygen?

Tue Dec 8 11:14:16 CST 2015

Hello Wendell,

thanks for your message.

I have managed yesterday to use the method recommended by Adrian (to 
whom I also adress my thanks).

This involved, among other things, transforming the internal DTD-s for 
the the chapters
into an external DTD file,
and verifying that they were all identical
(which was in fact originally not the case, because I had been 
progressively enriching the structure;
while editing the chapters one by one  :-)

I also had to diversify my XSLT strategy
because the original XSLT script, which worked fine with the chapters,
which are subtrees
did not work with the global thesaurus tree,
because the XPath references were too short ...

But in the end it worked fine,
and remained lightning fast,
even when going through 6000 entries
(instead of three times 2000 entries)
[I have 3 chapters so far, and will have 10 chapters in the end]

I have also been wondering whether I should write a DTD for the master 
document ...,
(but have so far not tried)
in the same way as I had to write yesterday evening a specific CSS for 
the master document.

My question concerning the place where the "information" is "stored"
was motivated by the fact that the series of videos
(for the "older", SGML-like, method)
showed buttons on which the virtual user was supposed to press,
in order to ENABLE the master file support
(and also because some menus indicated that the user
had to choose between several "possible master files"
and I imagined that the result of that customizing would be stored
somewhere in a file hidden the cryptic place called 
"%APPDATA%\Roaming\com.oxygenxml"
(or something of the sort .... I have not yet tried to SEE it ...)

I am relieved to realize that many things are now much easier than they 
were,
for people who work with complex scripts as Tamil
(my first experience with this matter go back to the time, in the eighties,
of writing Escape sequences for entering a user-defined "font"
in the memory of a dot-matrix printer, at the time of Dos 2.0

We have gone a long way :-)

Cheers
