cascadia is a library for Go that provides a CSS selector engine, allowing you to use CSS selectors to select elements from an HTML document.

It is built on top of the html package in the Go standard library, and provides a more efficient and powerful way to select elements from an HTML document.

cheerio is a popular JavaScript library that allows you to interact with and manipulate HTML and XML documents in a similar way to how you would with jQuery in a browser. It is a fast, flexible, and lean implementation of core jQuery designed specifically for the server.

One of the main benefits of using cheerio is that it allows you to use jQuery-like syntax to navigate and m anipulate the Document Object Model (DOM) of an HTML or XML document, making it easy to work with.

cheerio supports CSS selectors though not XPath.

Example Use


package main

import (
  "fmt"
  "github.com/andybalholm/cascadia"
  "golang.org/x/net/html"
  "strings"
)

func main() {
  // Create an HTML string
  html := `<html>
        <body>
          <div id="content">
            <p>Hello, World!</p>
            <a href="http://example.com">Example</a>
          </div>
        </body>
      </html>`

  // Parse the HTML string into a node tree
  doc, err := html.Parse(strings.NewReader(html))
  if err != nil {
    fmt.Println("Error:", err)
    return
  }

  // Compile the CSS selector
  sel, err := cascadia.Compile("p")
  if err != nil {
    fmt.Println("Error:", err)
    return
  }

  // Use the Selector.Match method to select elements from the document
  matches := sel.Match(doc)
  if len(matches) > 0 {
    fmt.Println(matches[0].FirstChild.Data)
    // > Hello, World!
  }
}
const cheerio = require('cheerio');
const $ = cheerio.load('<html><head><title>My title</title></head><body><h1 class='name'>Hello World!</h1></body></html>');
// use css selectors
console.log($('title').text()); // My title
console.log($('.name').text()); // Hello World!

// select multiple elements
const $ = cheerio.load('<html><body><ul><li>item 1</li><li>item 2</li></ul></body></html>');
$('li').each(function(i, elem) {
  console.log($(this).text());
});

// modify elements
const $ = cheerio.load('<html><body><h1>Hello World!</h1></body></html>');
$('h1').text('Hello, Cheerio!');
console.log($.html());
