Xassist is an SGML and XML quality control suite that provides users with the ability to correct structure and content errors. Xassist Parser includes five XML parsers and two SGML parsers which parse and correct in recursive, batch or single file mode; a file drag and drop facility; and cursor positioning at each error allowing the correction and re-parsing of text.
