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.

html5-parser is a Python library for parsing HTML and XML documents.

A fast implementation of the HTML 5 parsing spec for Python. Parsing is done in C using a variant of the gumbo parser. The gumbo parse tree is then transformed into an lxml tree, also in C, yielding parse times that can be a thirtieth of the html5lib parse times. That is a speedup of 30x. This differs, for instance, from the gumbo python bindings, where the initial parsing is done in C but the transformation into the final tree is done in python.

It is built on top of the popular lxml library and provides a simple and intuitive API for working with the document's structure.

html5-parser uses the HTML5 parsing algorithm, which is more lenient and forgiving than the traditional XML-based parsing algorithm. This means that it can parse HTML documents with malformed or missing tags and still produce a usable parse tree.

To use html5-parser, you first need to install it via pip by running pip install html5-parser. Once it is installed, you can use the html5_parser.parse() function to parse an HTML document and create a parse tree. For example:

``` from html5_parser import parse

html_string = "Hello, World!" root = parse(html_string) print(root.tag) # html ` You can also use `html5_parser.parse() with file-like objects, bytes or file paths.

Once you have a parse tree, you can use the find() and findall() methods to search for elements in the document similar to BeautifulSoup.

html5-parser also supports searching using xpath, similar to lxml.

Example Use


```javascript 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 = "

Hello, world!

"; parser.write(html); parser.end(); ```
```python from html5_parser import parse html_string = "Hello, World!" root = parse(html_string) print(root.tag) # html body = root.find("body") # or find all print(body.text) # "Hello, World!" for el in root.findall("p"): print(el.text) # "Hello ```
