Converting XML to JSON in Java: Rapid Solutions

When working with XML and JSON data, it's often necessary to convert between the two formats. Java provides various tools to facilitate this conversion quickly and efficiently.

One of the recommended libraries for this task is JSON in Java. Here's how to use it:

1. Add the Maven dependency to your project:

<dependency>
  <groupId>org.json</groupId>
  <artifactId>json</artifactId>
  <version>20180813</version>
</dependency>

2. Utilize the XML.java class:

import org.json.JSONObject;
import org.json.XML;
import org.json.JSONException;

// ...

// Sample XML string
String testXmlString = "<?xml version=\"1.0\" ?><test attrib=\"moretest\">Turn this to JSON</test>";

try {
    // Convert XML to JSON
    JSONObject xmlJsonObj = XML.toJSONObject(testXmlString);

    // Pretty-print the JSON result
    String jsonPrettyPrintString = xmlJsonObj.toString(PRETTY_PRINT_INDENT_FACTOR);
    System.out.println(jsonPrettyPrintString);
} catch (JSONException je) {
    System.out.println(je.toString());
}

3. Expected output:

{
    "test": {
        "attrib": "moretest",
        "content": "Turn this to JSON"
