* xml.el (xml--parse-buffer): Use xml-syntax-table. (xml-parse-tag): Likewise, and avoid changing entity tables. (xml-syntax-table): Define from scratch, making sure not to give x2000 and other Unicode spaces whitespace syntax, since those are not spaces in XML. (xml-parse-fragment): Delete unused function. (xml-name-start-char-re, xml-name-char-re, xml-name-re) (xml-names-re, xml-nmtoken-re, xml-nmtokens-re, xml-char-ref-re) (xml-entity-ref, xml-pe-reference-re) (xml-reference-re,xml-att-value-re, xml-tokenized-type-re) (xml-notation-type-re, xml-enumeration-re, xml-enumerated-type-re) (xml-att-type-re, xml-default-decl-re, xml-att-def-re) (xml-entity-value-re): Use syntax references in regexps where possible; no need to define inside a let-binding. (xml-parse-dtd): Use xml-pe-reference-re. (xml-entity-or-char-ref-re): New defconst. (xml-parse-string, xml-substitute-special): Use it.
