我正在尝试使用 json 库将 xml 转换为特定格式的 json。 xml 已转换为 json，但我不知道如何从中获取自定义值。
谁能告诉我一些解决方案
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
<?xml version="1.0"?>

最佳答案
我建议您考虑使用 XSLT 将源 XML 转换为 XML 版本，以便更轻松地转换为您正在寻找的 JSON。
或者，您可能需要使用 SAX 解析器来迭代 XML 并以编程方式创建 JSON。
