HTML Parser

Parses HTML text and calls callbacks on found elements.

The given HTML doesn't have to be valid. It tries any string to be parsed.

Zero dependencies. Create an issue if you found any HTML code parsed in a wrong way.

See tests for examples.

Installation

npm i lite-html-parser

  opentag (name) { console.log({ opentag: name }) },

  attribute (name, value) { console.log({ attribute: [name, value] }) },
  text (text) { console.log({ text }) },

})
