Parsing HTML is a automated task, performed by (so called) HTML parsers. They have two main purposes:

  • HTML traversal: offer a 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.
