What is parse5?

The parse5 npm package is a fast full-featured specification-compliant HTML parser for Node.js. It allows users to parse HTML documents and manipulate the resulting document tree structure. The package provides a variety of modules for parsing, serializing, and tree adaptation based on the DOM (Document Object Model) interface.

What are parse5's main functionalities?

Parsing HTML

This feature allows you to parse an HTML string into a document tree that can be manipulated or queried.

const parse5 = require('parse5');
const html = '<!DOCTYPE html><html><head></head><body>Hi there!</body></html>';
const document = parse5.parse(html);

Serializing Document

This feature enables you to serialize a document tree back into an HTML string.

const parse5 = require('parse5');
const document = parse5.parse('<!DOCTYPE html><html><head></head><body>Hi there!</body></html>');
const html = parse5.serialize(document);

Streaming

This feature allows you to use parse5 in a streaming mode, which is useful for processing large HTML documents without loading them entirely into memory.

const parse5 = require('parse5');
const fs = require('fs');
const file = fs.createReadStream('example.html');
const parser = new parse5.SAXParser();
parser.on('text', (text) => {
  console.log(text);
});
file.pipe(parser);

Tree Adapters

This feature allows you to use different tree adapters to interact with the parsed document tree in a way that is compatible with other libraries or your own custom requirements.

const parse5 = require('parse5');
const htmlparser2Adapter = require('parse5-htmlparser2-tree-adapter');
const html = '<!DOCTYPE html><html><head></head><body>Hi there!</body></html>';
const document = parse5.parse(html, { treeAdapter: htmlparser2Adapter });
