What it is

+ + + +

PSGML Mode is a mode for editing, umm, SGML and XML documents in emacs. It can parse a DTD and help you insert the right tags in the right place, knows about tags' attributes and can tell you in which contexts a tag can be used. If you give it the right DTD, that is. But even without a DTD, it can save you some typing since pressing C-c/ will close an open -tag automatically.

Where to get it

Most newer emacsen come with PSGML mode preinstalled. You can find out whether your emacs has it with the locate-library command. In Emacs, type M-x locate-library and enter psgml. Emacs will tell -you if it found it or not.

Using CATALOG files

The easiest way to teach PSGML mode about a DTD is by adding it to your own CATALOG. Here is an example of how you can set that up for the -Docbook XML DTD.

  1. Get the Docbook XML DTD -zip archive from docbook.org

  2. Go somewhere in your working directory and do

             cd dtd/docbook-xml
             unzip -a <docbook XML DTD zip archive>

    in it. By maintaining your own CATALOG, it is easy to add more DTD's without changing your emacs settings. (How about that HTML 4.01 DTD you always wanted to get from W3C ? The -DTD is in the zip archives and tarballs available on the site.)

That's it. Now you are ready to tell emacs all about PSGML mode and -that funky CATALOG
