How Can I Quickly Convert XML to JSON in Java?

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

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());
}

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