htmlparser2 is a Node.js library for parsing HTML and XML documents. It works by building a tree of elements, similar to the Document Object Model (DOM) in web browsers. This allows you to easily traverse and manipulate the structure of the document.

htmlparser2 is a low-level html tree parser but it can still be useful in web scraping as it's a powerful tool for HTML restructuring and serialization.

Example Use


const htmlparser = require("htmlparser2");
const parser = new htmlparser.Parser({
    onopentag: (name, attribs) => {
        console.log(`Opening tag: ${name}`);
    },
    ontext: (text) => {
        console.log(`Text: ${text}`);
    },
    onclosetag: (name) => {
        console.log(`Closing tag: ${name}`);
    }
}, {decodeEntities: true});

const html = "<p>Hello, <b>world</b>!</p>";
parser.write(html);
parser.end();
