How to convert XML file into properties file – Java

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
   <properties>
 <comment>Support Email</comment>
 <entry key="email.support">donot-spam-me@nospam.com</entry>
   </properties>

In this example, we show you how to use loadFromXML() method to load above XML file into a properties object, and get the key “email.support” value via getProperty() method.

package com.mkyong;
 
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
 
public class PropertiesXMLExample
{
    public static void main(String[] args) throws IOException
    { 
     Properties props = new Properties();
 
     InputStream is = new FileInputStream("c:/email-configuration.xml");
     //load the xml file into properties format
     props.loadFromXML(is);
 
     String email = props.getProperty("email.support");
 
     System.out.println(email);
 
    }
}

Output
The above example will print out the value of properties key : “email.support” :

donot-spam-me@nospam.com
