XML: extensible markup language, a language similar to HTML. It has no predefined tags and uses document type definition (DTD) to organize data. The format is uniform, cross-platform and language have long been recognized in the industry. For details, refer to Google or Baidu. Compared with JSON, a lightweight data exchange format, XML can be cal
As far as readability and scalability are concerned, JSON and XML are comparable.
In terms of coding difficulty, JSON is a bit simpler than XML, and it's best to write XML with the XML editor, which makes it easy to make mistakes
