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.

xpath is a library for Go that allows you to use XPath expressions to select elements from an HTML document. It is built on top of the html package in the Go standard library, and provides a way to select elements from an HTML document using XPath expressions, which are more powerful and expressive than CSS selectors.

Example Use

```go package main import ( "fmt" "github.com/andybalholm/cascadia" "golang.org/x/net/html" "strings" ) func main() { // Create an HTML string html := `

Hello, World!

Example

` // 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! } } ```

```go package main

import ( "fmt" "github.com/antchfx/xpath" "golang.org/x/net/html" "strings" )

func main() { // Create an HTML string html := `

Hello, World!

Example

    </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 XPath expression expr, err := xpath.Compile("//p") if err != nil { fmt.Println("Error:", err) return }

// Use the Evaluate method to select elements from the document nodes, err := expr.Evaluate(xpath.NodeNavigator(doc)) if err != nil { fmt.Println("Error:", err) return } if nodes.MoveNext() { fmt.Println(nodes.Current().Value()) // > Hello, World! } } ```
