Finding schema files...

Well, like most XML tools, nxml-mode seems to be "oversized".

Basically, I don't want to place my schema files on a webserver. Why should I? And how do I guarantee they stay
current? xmllint, on the other hand, didn't even accept "file://..." --- luckily, it has a command line
option, although putting the path into the XML would have been nice.

nxml doesn't even allow any specs inside the XML file; instead it's using some obscure repository. Same as
before, I don't want my schema files to be installed on the system (it would have to be symlinks back into my
working copy anyway, but unfortuntely someone other than me checking out the stuff won't be getting
this). I don't even want to add "pointers" into my working copies into some private configuration file of
me. I just want to associate an XML file with a schema file, nothing more. I don't even want to "search" for
the schema file --- I know where it is! Believe it or not, I just happen to know the layout of my source repository.

Is there any way to stick something into an XML file that makes emacs or nxml use the correct schema file, a
SIMPLE file path? Even if it's an elisp fragment that needs to be installed so emacs reads a line like <!--
XMLSchema: ../../Schema/Data/foo.rnc --> and does the right thing? Of course, it would be nicer if
nothing had to be done to make it work.

Or am I really the only one using XML for stuff that's not some obscure worldwide distributed collection of
magic processing rules, pulling datatypes from asia into rules from china to determine how to process
documents assembled from france and italy with an encoding table from russia?

So work without a schema? You've pushed yourself into a corner there

Re: Finding schema files...

If rng-schema-locating-files contains "schemas.xml" (which I think it
does by default.  Try `C-h v rng-schema-locating-files' to verify), you
can put a file named schemas.xml in the same directory as your document.

As for the format of that file, see the link that Kenneth J. Hughes
posted.

In short, you can match a file name pattern, an absolute file name, a
namespace used, the document element name, a doctype declaration public
IS, and more, against an RNC schema.

You can also specify a default schema.

If rng-schema-locating-files contains "schemas.xml", and you put a
schemas.xml file with this content in the same directory as the XML
documents themselves, that should do the trick:

<?xml version="1.0"?>
<locatingRules xmlns="http://thaiopensource.com/ns/locating-rules/1.0">
  <default uri="../../Schema/Data/foo.rnc"/>
</locatingRules>

If you think "what do I need with a bunch of identical extra schemas.xml
files?", then create a single one, and add its location to
rng-schema-locating-files,

I used to have a hook function for nxml-mode that read the PI that
<oXygen/> inserts in XML files to find the schema and used that to tell
nxml-mode to find the schema.  It wasn't hard to do, but I don't have it
anymore after I made both an <oXygen/> framework and a nxml-mode schemas
file for the schema (for the XSpec XSLT/XQuery testing framework) so
people would stop putting idiosyncratic schema locations in PIs in shared
XSpec test files.

Huh...?  Is that possible?  I didn't know that.

Now I've experiemented.  Original poster, please try this:

Make sure that the first element (car) of rng-schema-locating-files is
"schemas.xml" (this is the default).

Then select from the menus 
 XML->Set Schema->File...
and select the name of the RNC file for your schema.

You will be prompted if you want to save this setting, and clicking on
"Yes" will save a connection between your XML file and the schema you
browsed to in a file called schemas.xml in the CWD.  The path to the
schema file will be relative to the schemas.xml file.

nxml-mode will create a schemas.xml file for you if one doesn't already
exist.

(define-key nxml-mode-map [f9] 'rng-set-schema-file)

as part of your .emacs helps. I use f9 now,
then tidy up the schemas file every few months

This as part of
(add-hook 'nxml-mode-hook
  (function (lambda()
	    (define-key nxml-mode-map [f5] 'sgml-comment)
	    (define-key nxml-mode-map [f9] 'rng-set-schema-file)
	    (define-key nxml-mode-map "\C-c\C-r" 'tag-region)
	    (setq nxml-slash-auto-complete-flag t)
	    (setq nxml-auto-insert-xml-declaration-flag t)
	    (setq nxml-default-buffer-file-coding-system (quote utf-8-dos))
	    (setq nxml-glyph-set (quote nxml-wgl4-glyph-set))
	    (setq rng-schema-locating-files '("/sgml/schemas.xml"))
	    (setq sgml-indent-data t)
	    (setq sgml-indent-step 2)
	
	    ))) ;; End of nxml mode specific hooks.

Note that this particular setting may be appropriate to the original
poster's use case.  This makes nxml look for a single schemas.xml file
in the directory "/sgml" (absolute path).

But the default value for rng-schema-locating-files should be
appropriate for the original poster.
