parse5 is a Node.js library for parsing and manipulating HTML and XML documents. It is designed to be fast and flexible, and it is commonly used in web scraping and web development projects.

parse5 is used by popular libraries such as Angular, Lit, Cheerio and many more. Unlike Cheerio parse5 is a low level html parsing library that might be useful directly in web scraping without higher level abstraction.

Chopper is a tool to extract elements from HTML by preserving ancestors and CSS rules.

Compared to other HTML parsers Chopper is designed to retain original HTML tree but eliminate elements that do not match parsing rules. Meaning, we can parse HTML elements and keep thei structure for machine learning or other tasks where data structure is needed as well as the data value.

Example Use

```javascript const parse5 = require("parse5"); // parse string const document = parse5.parse('Hello World!'); console.log(document); // html tree can be traversed as javascript object: const body = document.childNodes[1]; console.log(body.childNodes[0].value); // "Hello World!" // and modified const newElement = parse5.parseFragment('

New Element

'); body.appendChild(newElement.childNodes[0]); console.log(parse5.serialize(document)); ```

```python HTML = """ Test

HELLO WORLD Do not want

<div id="footer"></div>

"""

CSS = """ div { border: 1px solid black; } div#main { color: blue; } div.iwantthis { background-color: red; } a { color: green; } div#footer { border-top: 2px solid red; } """

extractor = Extractor.keep('//div[@class="iwantthis"]').discard('//a') html, css = extractor.extract(HTML, CSS)
