Demand:

The server returns the XML data and needs to parse the XML data to generate the JSON file

The conversion here can only transform the content behind the tag, the label properties can not be converted, the format is also more chaotic, it is recommended to use Net.sf.json for conversion, you can use Oxstream to convert

Tools are human productivity.
