A simple guide to XML and JSON conversion

XML (Extensible Markup Language) and JSON (JavaScript Object Notation) are two commonly used data formats for passing and storing data between applications. In Android development, it is often necessary to convert data from XML format to JSON format, or vice versa. This article will introduce in detail how to realize the mutual conversion between XML and JSON, and provide the corresponding source code.

1. XML to JSON

XML to JSON conversion requires parsing the XML data into appropriate data structures and then converting it into JSON format. In Android, you can use the XmlPullParser class to parse XML data, and use the JSONObject and JSONArray classes to build JSON objects and arrays.

The following is a sample XML data:

<book>
  <title>Harry Potter</title>
