我有一个JSON文件，我希望在JAVA中将其转换为XML，以使用即将出现的XML结构处理一些不同的东西。 我的文件看起来像这样：
{

我使用了org.json库，并尝试了一些其他库，如JETTISON，从这个人创建一个xml文件，但大多数`XML.toString（）“方法都无法处理此文件中的JSONArray。它只会产生奇怪的引号输出等。 是否有可以处理此类JSON结构的库？如果不是：我应该如何处理这种文件类型？
**编辑**
我在互联网上看到了这个文件似乎和我的结构相同。但我的编码错了，有谁知道为什么？
这是：
{"menu": {
"header": "SVG Viewer",
"items": [
{"id": "Open"},
{"id": "OpenNew", "label": "Open New"},
null,
{"id": "ZoomIn", "label": "Zoom In"},
{"id": "ZoomOut", "label": "Zoom Out"},
{"id": "OriginalView", "label": "Original View"},
null,
{"id": "Quality"},
{"id": "Pause"},
{"id": "Mute"},
null,
{"id": "Find", "label": "Find..."},
{"id": "FindAgain", "label": "Find Again"},
{"id": "Copy"},
{"id": "CopyAgain", "label": "Copy Again"},
{"id": "CopySVG", "label": "Copy SVG"},
{"id": "ViewSVG", "label": "View SVG"},
{"id": "ViewSource", "label": "View Source"},
{"id": "SaveAs", "label": "Save As"},
null,
{"id": "Help"},
{"id": "About", "label": "About Adobe CVG Viewer..."}
]
}}
最初提供的是bei org.json。
答案 0 :(得分：1)
xml节点未正确显示的原因是JSONArray的名称。 出于某种原因，如果我从＆＃34;内容＆＃34;重命名JSONArray，它会正确显示。到＆＃34; _content＆＃34;或其他什么。
对我来说，它看起来像是来自org.json的错误。
此处使用的代码：
Scanner scan = new Scanner(new File(jsonFile));
String jsonData = "";
while (scan.hasNext()) {
jsonData += scan.nextLine();// + "\n";
}
scan.close();
JSONObject json = new JSONObject(jsonData);
String xml = org.json.XML.toString(json);
System.out.println(xml);
正如我之前提到的，只是JSONArray的重命名解决了这个问题。 重命名后，输出如下所示：

在重命名之前，它看起来像这样：
