首先要先 pod Kanna
在 ViewController

import Kanna

 override func viewDidLoad() {
        super.viewDidLoad()
       let loginurl =  "https://translate.google.com/"
        if let doc = try? HTML(html: loginurl, encoding: .utf8) {
            print(doc.title)
            
            // Search for nodes by CSS
            for link in doc.css("body, script") {
                print(link.text)
                print(link["src"])
            }
        }
        
        
    }
