如何将xml转换为有效的json字符串

问：

我有一些XML我想输入到api端点，但是，我需要将xml转换为json有效字符串才能这样做。当我在网上搜索将xml转换为JSON或“JSON有效字符串”时，我发现解析器可以将xml转换为与xml具有相同结构的json对象。我想要一些不同的东西，我想将xml转换为一个字符串，该字符串将用作json字典中的单个值。

这意味着我需要将新行转换为“\n”。此外，结果需要通过 JSON lint 验证。https://jsonlint.com。

例如，假设我有以下 swift 代码：

import UIKit
import TableMVVM

class SubMenuChoice: NibView, HasViewModel {

    @IBOutlet var titleLabel: UILabel!
    @IBOutlet var detailsLabel: UILabel!
    @IBOutlet var viewToGradient: BottomLeftToTopRightGradient!

    var viewModel: ViewModel = .fallBack {
        didSet {
            self.titleLabel.text = viewModel.titleText
            self.detailsLabel.text = viewModel.detailText
            self.viewToGradient.layer.cornerRadius = 16
            self.viewToGradient.clipsToBounds = true
            self.viewToGradient.layer.borderColor = UIColor.white.cgColor
            self.viewToGradient.layer.borderWidth = 0.2
        }
    }
}

然后，我通过换掉文本回车符的新行，将其转换为有效的一行 json 字符串。

{"MyJSON" : "import UIKit\nimport TableMVVM\n\nclass SubMenuChoice: NibView, HasViewModel {\n\n    @IBOutlet var titleLabel: UILabel!\n    @IBOutlet var detailsLabel: UILabel!\n    @IBOutlet var viewToGradient: BottomLeftToTopRightGradient!\n\n    var viewModel: ViewModel = .fallBack {\n        didSet {\n            self.titleLabel.text = viewModel.titleText\n            self.detailsLabel.text = viewModel.detailText\n            self.viewToGradient.layer.cornerRadius = 16\n            self.viewToGradient.clipsToBounds = true\n            self.viewToGradient.layer.borderColor = UIColor.white.cgColor\n            self.viewToGradient.layer.borderWidth = 0.2\n        }\n    }\n}\n"}

这是我需要转换为单行的文本，有效的 json 字符串值：

import UIKit
import TableMVVM

class SubMenuChoice: NibView, HasViewModel {

    @IBOutlet var titleLabel: UILabel!
    @IBOutlet var detailsLabel: UILabel!
    @IBOutlet var viewToGradient: BottomLeftToTopRightGradient!

    var viewModel: ViewModel = .fallBack {
        didSet {
            self.titleLabel.text = viewModel.titleText
            self.detailsLabel.text = viewModel.detailText
            self.viewToGradient.layer.cornerRadius = 16
            self.viewToGradient.clipsToBounds = true
            self.viewToGradient.layer.borderColor = UIColor.white.cgColor
            self.viewToGradient.layer.borderWidth = 0.2
        }
    }
}

extension SubMenuChoice {
    struct ViewModel: HasFallBack {
        let titleText: String
        let detailText: String

        static var fallBack: Self {
            .init(titleText: "-", detailText: "-")
        }
    }
}

当我尝试用新的行文字交换新行时，它会破坏 JSON linter。

我怀疑我不是第一个做这种事情的人，所以我希望有人知道将 xml 转换为有效 json 字符串的公式。请帮忙。谢谢。
