与Swiftsoup挣扎并解析html-尝试获取文本时获取nil

Question

我正在尝试解析一些html类并在textview中显示。 Here's a screenshot of the webpage with the html classes.我需要“ t-gurmukhi”课程。

我已经成功打印了p.tag-links，但是t-gurmukhi给了我零。

我正在使用SwiftSoup库尝试执行此操作，并使用Alamofire来获取链接。到目前为止，这是我的代码：

 import UIKit
 import Alamofire
 import SwiftSoup

 class HtmlDecodeViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()

    downloadHTML()
}

func downloadHTML() {

    let getURL = "https://www.someurl.com"

    Alamofire.request(getURL, method: .post, parameters: nil, encoding: URLEncoding.default).validate(contentType: ["application/x-www-form-urlencoded"]).response { (response) in

        if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
            do {
                let html: String = utf8Text
                let doc: Document = try SwiftSoup.parse(html)

                    for infoTags in try! doc.select("p.tag") {
                        let someText = try infoTags.text()
                        self.hukamInfo.text = someText
                    }

                let els: Elements = try doc.getElementsByClass("t-tag")
                let el: Element? = els.first()//get first element
                print(try "\(String(describing: el?.text()))")

            } catch let error {
            // an error occurred
            print(error.localizedDescription)
            }
        }
        }

}
