HTML parsers are software for automated Hypertext Markup Language (HTML) parsing. They have two main purposes:
HTML traversal: offer an interface for programmers to easily access and modify of the "HTML string code". Canonical example: DOM parsers.HTML clean: to fix invalid HTML and to improve the layout and indent style of the resulting markup. Canonical example: HTML Tidy.* Latest release (of significant changes) date.**
sanitize (generating standard-compatible web-page, reduce spam, etc.) and
clean (strip out surplus presentational tags, remove XSS code, etc.) HTML code.*** Updates HTML4.X to XHTML or to HTML5, converting deprecated tags (ex. CENTER) to valid ones (ex. DIV with
style="text-align:center;").
