Re: psgml dtds

More dtd problems. When I write a text xml file and a dtd for it, as in the JAXP tutorial, any attempt to indent the buffer text leads to the following problem. Signaling: (wrong-type-argument stringp nil) string-match("^\\(+//\\|-//\\|\\)\\(\\([^/]\\|/[^/]\\)+\\)//\\([^ ]+\\) \\(\\([^/]\\|/[^/]\\)*\\)//\\(\\([^/]\\|/[^/]\\)*\\)\\(//\\(\\([^/]\\|/[^/]\\)*\\)\\)?" nil) sgml-canonize-pubid(nil) sgml-setup-doctype("slideshow" (nil "./slideshow.dtd" . "/home/pbw/src/xml/")) sgml-do-doctype() sgml-parse-markup-declaration(prolog) sgml-parse-prolog() sgml-load-doctype() sgml-need-dtd() sgml-parse-to(2) sgml-find-element-of(1) byte-code("..." [sgml-find-context-of sgml-find-element-of] 2) sgml-indent-line() #<compiled-function nil "...(9)" [sgml-indent-step insert-tab indent-line-function] 1 ("/usr/local/lib/xemacs/xemacs-packages/lisp/psgml/psgml.elc" . 25016) nil>() call-interactively(sgml-indent-or-tab) The difficulty is that my DOCTYPE is a SYSTEM followed by the local filename of the dtd. In the call to `sgml-setup-doctype' the pubid is `nil'. `sgml-canonize-pubid' however, makes no provision for a `nil' pubid. (defun sgml-canonize-pubid (pubid) (if (string-match sgml-formal-pubid-regexp pubid) (concat .... It is called by the following code in sgml-setup-doctype (cond (external ;; James addition - set the sgml-declaration (let ((decl (sgml-catalog-lookup sgml-catalog-files nil 'dtddecl (sgml-canonize-pubid (car external))))) Hasn't the dtddecl been excluded from XML?
