UITextView:如何从加载XML的字符串中设置'\n'？

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var textView: UITextView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let xmlString = "<root><text>这是第一行。\n这是第二行。</text></root>"
        let processedString = processXMLString(xmlString)
        textView.text = processedString
    }
    
    func processXMLString(_ xmlString: String) -> String {
        // 解析XML字符串并替换换行符
        // 这里使用了AEXML库来解析XML字符串
        let xmlDoc = try! AEXMLDocument(xml: xmlString)
        let textNode = xmlDoc.root["text"]
        let processedString = textNode.stringValue.replacingOccurrences(of: "\\n", with: "\n")
        return processedString
    }
}
