* test/automated/xml-parse-tests.el: New file.
* lisp/xml.el (xml--parse-buffer): New function. Move most of
xml-parse-region here.
(xml-parse-region): Copy region into a temporary buffer, since
parameter entity substitution requires changing buffer contents.
Use xml--parse-buffer.
(xml-parse-file): Use xml--parse-buffer.
(xml-parse-dtd): Make parameter entity substitution work right.
* xml.el (xml-*-re): Convert defvars into defconsts, and
eval-and-compile them so eval-and-compile works on derivatives.
(xml--entity-replacement-text): Use eval-and-comple.
(xml-parameter-entity-alist): New variable.
(xml-parse-region, xml-parse-fragment): Preserve previous values
of xml-entity-alist and xml-parameter-entity-alist, so that
repeated calls on different documents do not change them.
(xml-parse-tag): Fix doctype regexp.
(xml--entity-replacement-text): New function.
(xml-parse-dtd): Use it. Don't handle system entities; doing that
properly requires url retrieval which is unimplemented.
(xml-escape-string): Doc fix.
(xml-parse-dtd, xml-parse-elem-type, xml-substitute-special):
Return to use of the -no-properties variants. There was
consensus on emacs-devel that the speed of these variants was
prefered since we are usually parsing files (from the internet
or on disk) instead of XML created in Emacs.
* xml.el (xml-substitute-special): Fix validity error messages to
actually show the unexpandable entity. Added validity error if &
isn't followed by an entity.
(xml-parse-tag): Concatnate any string following the a
<![CDATA[]]> section to the parsed CDATA.
* xml.el (xml-maybe-do-ns, xml-parse-tag): Produce elements in the
form
(("ns" . "element") (attr-list) children) instead of
((:ns . "element") (attr-list) children) in order to reduce the
number of symbols used.
(xml-skip-dtd): Change to use xml-parse-dtd but set
xml-validating-parsing to nil.
(xml-parse-dtd): Parse entity deleclarations in DOCTYPEs.
(xml-substitute-entity): Remove in favor of new entity substitution.
(xml-substitute-special): Rewrite in to substitute complex
entities from DOCTYPE declarations.
(xml-parse-fragment): Parse fragments from entity deleclarations.
(xml-parse-region, xml-parse-tag, xml-parse-attlist)
(xml-parse-dtd, xml-substitute-special): Make validity checks
conditioned on xml-validating-parser. Add "Not Well Formed" to
error messages about well-formedness.
indentation to text nodes and write empty elements as empty tags
instead of opening and closing tags.
(xml-debug-print): Take optional indent-string argument.
(xml-print): Alias for xml-debug-print.
