Did you turn on XML mode for this buffer, or the generic SGML mode?

I'm having problems with fontification myself. I have the following in
my .emacs:

autoload 'xml-mode "psgml" "psgml" t)
(defun my-xml-mode-hook ()
  (cond (window-system
         (setq sgml-set-face t)
         (setq sgml-indent-data t))))

(add-hook 'sgml-mode-hook 'my-xml-mode-hook)

When I open an xml file it is initially not fontified. However if I
select a region and do C-M-\ it then fontifies.

Any ideas why that would be ?

That's because PSGML uses its own fontification mechanism, and avoids
font-lock.  PSGML does fontification lazily, in a way, so it only
fontifies things that you change.  You can also go to a line
and hit TAB -- then it will fontify everything up to that line.

When PSGML was written, font-lock was probably not powerful enough for
proper SGML font-locking: you can change the < and > characters in
SGML, so regular expressions don't work.

I don't think that's the issue, since PSGML does not support different
values of stago, etago, and tagc (other than the default values "<",
"</", and ">"):

| File: psgml.info,  Node: SGML declaration,  Next: Managing the DTD,  Prev: 
Validate,  Up: Top
|
| SGML Declaration
****************|
|
|    PSGML does not understand the SGML declaration, it accepts one in the
| file but it is ignored.  If you have the SGML declaration in another
| file you can make `sgmls' use it when you use the `C-c C-v'
| (`sgml-validate') command (*note Validate::.).
|
|    PSGML has some options in what features it uses and what markup it
| creates.  You have to set these options to make PSGML's behavior
| consistent with your SGML declaration and personal preferences.
|
|  - User Option: sgml-omittag
|      Set this to `t' if the SGML declaration has `OMITTAG YES' and to
|      `nil' otherwise.
|
|  - User Option: sgml-shorttag
|      Set this to `t' if the SGML declaration has `SHORTTAG YES' and to
|      `nil' otherwise.
|
|  - User Option: sgml-always-quote-attributes
|      If non-nil, quote all attribute values inserted after finishing
|      edit attributes.  If this variable is `nil' and `sgml-shorttag' is
|      non-`nil', attribute values that consists of only name characters
|      will not be quoted.
|
|  - User Option: sgml-minimize-attributes
|      Determines minimization of attributes inserted by edit-attributes.
|      If non-nil, omit attribute name if the attribute value is from a
|      token group.  If `max', omit attributes with default value.
|      Minimization will only be done if they produce legal SGML (assuming
|      `sgml-omittag' and `sgml-shorttag' are set correctly).

Oh.  So why does it things this way, then?

That's fine... I just wanted to make sure it wasn't a config issue on
my end.

Thanks for the info.

Out of the box SGML mode. (along with xslt-process as the minor mode).

No.  I add nothing to the auto-mode-alist for an xml extension.  Suggestions?

Out of the box, Emacs's sgml-mode does not have xslt-process, does not do
indentation, and does not know anything about XML.

You might want to try:

http://savannah.gnu.org/cgi-bin/viewcvs/emacs/emacs/lisp/textmodes/sgml-mode.el?rev=HEAD

which adds XML support and indentation to "out of the box SGML mode".

That appears to be the same module included in my install (although
more current, is that what you were implying?), in
/emacs-21.3/lisp/textmodes/sgml-mode.el.  

Also, from the Menu->SGML->File Options, there is *Indent Step*, and
*Indent Data*.  Are we talking about two different SGML modes?

As indirectly mentioned in my previous message, "more current" in this case
implies "adds XML support and indentation".

OK, I found buried in the XAE package, a version of PSGML.  So, that
is in fact what I'm using.  I removed that and retrieved the current
PSGML:

Emacs  : GNU Emacs 21.3.1 (i386-msvc-nt5.1.2600)
 of 2003-03-27 on buffy
Package: psgml.el 1.3.1

I guess I'll submit a bug-report.

Thanks.

Indentation problems in SGML mode

[Jeffery B. Rancier]

I'm seeing peculiar indentation in some of my XML files.  For example,
if I start with the following:

<?xml version="1.0"?>
<project name="ScreenDesigner" default="help" basedir=".">
    <!-- Project directories -->
    <property name="src.dir"              value="src"/>
    <property name="doc.dir"              value="doc"/>
    <property name="dist.dir"             value="dist"/>
    <property name="lib.dir"              value="lib"/>
    <property name="bin.dir"              value="bin"/>

    <!-- Temporary build directories -->
    <property name="build.dir"            value="build"/>
    <property name="build.classes"        value="${build.dir}/classes"/>
    <property name="build.doc"            value="${build.dir}/doc"/>
    <property name="build.lib"            value="${build.dir}/lib"/>

and run mark-whole-buffer, and run indent-region, I get the
following.  Is a bug in SGML mode?

<?xml version="1.0"?>
<project name="ScreenDesigner" default="help" basedir=".">
  <!-- Project directories -->
  <property name="src.dir"              value="src"/>
    <property name="doc.dir"              value="doc"/>
      <property name="dist.dir"             value="dist"/>
	<property name="lib.dir"              value="lib"/>
	  <property name="bin.dir"              value="bin"/>

	    <!-- Temporary build directories -->
	    <property name="build.dir"            value="build"/>
	      <property name="build.classes"        value="${build.dir}/classes"/>
		<property name="build.doc"            value="${build.dir}/doc"/>
		  <property name="build.lib"            value="${build.dir}/lib"/>
