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.

goquery brings a syntax and a set of features similar to jQuery to the Go language. goquery is a popular and easy-to-use library for Go that allows you to use a CSS selector-like syntax to select elements from an HTML document.

It is based on Go's net/html package and the CSS Selector library cascadia. Since the net/html parser returns nodes, and not a full-featured DOM tree, jQuery's stateful manipulation functions (like height(), css(), detach()) have been left off.

Also, because the net/html parser requires UTF-8 encoding, so does goquery: it is the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML. See the wiki for various options to do this. Syntax-wise, it is as close as possible to jQuery, with the same function names when possible, and that warm and fuzzy chainable interface. jQuery being the ultra-popular library that it is, I felt that writing a similar HTML-manipulating library was better to follow its API than to start anew (in the same spirit as Go's fmt package), even though some of its methods are less than intuitive (looking at you, index()...).

goquery can download HTML by itself (using built-in http client) though it's not recommended for web scraping as it's likely to be blocked.

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)); ```

```go package main import ( "fmt" "github.com/PuerkitoBio/goquery" ) func main() { // Use goquery.NewDocument to load an HTML document // This can load from URL doc, err := goquery.NewDocument("http://example.com") // or HTML string: doc, err := goquery.NewDocumentFromReader("some html") if err != nil { fmt.Println("Error:", err) return } // Use the Selection.Find method to select elements from the document doc.Find("a").Each(func(i int, s *goquery.Selection) { // Use the Selection.Text method to get the text of the element fmt.Println(s.Text()) // Use the Selection.Attr method to get the value of an attribute fmt.Println(s.Attr("href")) }) } ```
