How to pretty print XML from Java?

Question

I have a Java String that contains XML, with no line feeds or indentations. I would like to turn it into a String with nicely formatted XML. How do I do this?

Answer 1

Underscore-java has static method U.formatXml(string). I am the maintainer of the project. Live example

import com.github.underscore.lodash.U;

public class MyClass {
    public static void main(String args[]) {
        String xml = "hello";

        System.out.println(U.formatXml("" + xml + ""));
    }
}

Output:

   
      hello
