psgml how to validate against schema

psgml how to validate against schema

[AngusC]

Hello

I am trying to validate an xml file against a schema.  The schema doc is
called appmetadata.xsd.  In emacs If I select from menu XML... Set Schema...
File and select file nothing happens.

If I select menu option Show Schema location I see message: Using vacuous
schema.

Anyone know what I am doing wrong?

I am using emacs v23.3.1 on windows.

Angus

I thought psgml only supported good old DTDs...?

exists a command `M-x sgml-validate' whose content is customizable.
Should validate xsd files too, given the executable is set correctly.

psgml DTD usage goes beyond validation.  It uses the DTD information
assist with inserting elements and edit attributes.

Sure. However, as far as a programm outside Emacs is called, just the 
results sent back, that shouldn't matter here.

The psgml usage of an external validator is just similar to the way
emacs handles compilation errors.

It can't use the external program to help with editing.  For that it
uses its built-in DTD parser (written in lisp).

Editing and validating are different issues.

Some sgml-forms will not work, when built upon use of dtd.
Please report that as a bug then.
Feel free to drop me a cc then.

As dtd are optional, no command should fail completely without.

Emacs calls an external programm for that. Should be able to play the 
results back.

AFAIS the work is basically done in line 1582 compile.el:

(start-file-process-shell-command (downcase mode-name)
						       outbuf command)

All you need to do is selecting the correct validation-command, when 
starting.
