How does htmlparser2.Parser work?

The htmlparser2.Parser is a parser for HTML documents that uses a stream-based approach to parse the document and emit events for different parts of the document, such as tags, attributes, and text. The parser can be customized through options and can handle different HTML dialects.

const htmlparser = require("htmlparser2");

const parser = new htmlparser.Parser({
  onopentag(name, attributes) {
    console.log("Open tag:", name);
    console.log("Attributes:", attributes);
  },
  ontext(text) {
    console.log("Text:", text);
  },
  onclosetag(name) {
    console.log("Close tag:", name);
  },
});

parser.write(" Hello world ");
parser.end();

This code creates a new htmlparser2.Parser instance and defines some event listeners that will be called as the parser encounters different parts of the HTML document. When parser.write() is called, the parser will start processing the input HTML string. Finally, parser.end() is called to signal the end of the input stream. When this happens, the parser will emit a "finish" event.
