Question

我有一个内容如下的xml文件：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="array_ngontay_kq">
        <item>Bạn là người đáng tin cậy.</item>
        <item>Bạn là người có óc xét đoán. </item>
    </string-array>
</resources>

然后我用HTMLReader得到了这个字符串数组，但是我的输出看起来像这样：

Báº¡n lÃ  ngÆ°á»i ÄÃ¡ng tin cáºy.
Báº¡n lÃ  ngÆ°á»i cÃ³ Ã³c xÃ©t ÄoÃ¡n.

这是我的代码：

let fileURL = Bundle.main.url(forResource: "BoiTay", withExtension: "xml")
        let xmlData = try! Data(contentsOf: fileURL!)
        let topic = "array_ngontay_kq"
        let document = HTMLDocument(data: xmlData, contentTypeHeader: "text/xml")
        for item in document.nodes(matchingSelector: "string-array[name='\(topic)'] item") {
                print(item.textContent)
            }

是否有解决此问题的方法，或者任何其他解决方案都可以在不使用HTMLReader的情况下做到这一点。对不起，我是XMLParse的新人，我在Swift中找不到关于这种xml文件的任何答案或教程。

Answer 1

首先，您最好检查您的commit(keyMutation, payload) { (arguments.length < 2) ? this.mutations[keyMutation](this.state) : this.mutations[keyMutation](this.state, payload); },是否真的在UTF-8中。我对越南语编码不熟悉，但是即使xml标头声明为BoiTay.xml，某些工具也可能会使用UTF-8以外的其他编码生成XML。

结果似乎是编码问题，而不是库或代码的错误。

请显示您的encoding="utf-8"的十六进制转储，包括第一个xmlData元素。

item

也许前256个字节就足够了。

顺便说一句，使用print(xmlData as NSData)并不是那么困难。（尽管这并不容易。）

这是您可以在Playground中测试的示例。

            //Silently igonore characters while content string is not ready
            return
        }
        currentText! += string
    }

let xmlText = """

"]]的内容测试此代码并获得与BoiTay.xml类似的结果，则问题肯定是编码问题。

（如果实际的xml比示例复杂，则可能需要修改此代码。）
