我正在尝试使用json库将xml转换为特定格式的json。 xml转换为json，但我不知道如何从中获取自定义的。
任何人都可以告诉我一些解决方案吗
我的代码如下所示
转换代码
File file = new File ("D:\\data.xml");
inputStream = new FileInputStream(file);
StringBuilder builder = new StringBuilder();
int ptr = 0;
while ((ptr = inputStream.read()) != -1 )
{
builder.append((char) ptr);
}
String xml = builder.toString();
JSONObject jsonObj = XML.toJSONObject(xml);
System.out.println(jsonObj);
data.xml中
<?xml version="1.0"?>

我建议您使用XSLT将源XML转换为XML版本，以便更容易地将其转换为您正在寻找的JSON。
或者，您可能需要使用SAX解析器迭代XML并以编程方式创建JSON。
