emacs sgml

Hello, I'm having trouble getting sgml to work in emacs. I'm getting the same error as this user here: http://www.redhat.com/archives/fedora-docs-list/2003-October/msg00046.html I installed all the emacs, docbook and sgml packages I could find. But I still get the error: XML requires a system ID after a public ID This is when I invoke xemacs like this: [144 13:33 gose@winters:~/fedora-docs/documentation-guide] xemacs documentation-guide-en.xml And run 'DTD -> Parse DTD'. Any ideas? ------------------------------------------- [root@winters gose]# rpm -qa | grep sgml sgml-common-0.6.3-14 psgml-1.2.5-1 [root@winters gose]# rpm -qa | grep emac xemacs-sumo-20031003-3 mew-xemacs-3.3-1 xemacs-sumo-el-20031003-3 emacs-leim-21.3-7 xemacs-21.4.14-3 xemacs-info-21.4.14-3 xemacs-el-21.4.14-3 xemacs-sumo-info-20031003-3 ddskk-xemacs-11.6.0-12 emacs-el-21.3-7 emacs-21.3-7 apel-xemacs-10.6-1 flim-xemacs-1.14.5-1 emacspeak-17.0-4 wl-xemacs-2.10.1-1.1 [root@winters gose]# rpm -qa | grep xml perl-libxml-perl-0.07-28 xml-common-0.6.3-14 libxml-devel-1.8.17-9 nxml-mode-0.20031031.1-0.1 libxml2-2.5.11-1 perl-libxml-enno-1.02-29 libxml-1.8.17-9 xmlto-0.0.15-1 libxml2-python-2.5.11-1 libxml2-devel-2.5.11-1 xmltex-20000118-14.1 [root@winters gose]# rpm -qa | grep docbook docbook-style-xsl-1.61.2-2.1 docbook-style-dsssl-1.78-2 docbook-dtds-1.0-22.1 docbook-utils-pdf-0.6.13-7 docbook-utils-0.6.13-7 ------------------------------------------- -- Scott Gose gose(a)mcs.anl.gov
