In Java, we can use the Properties#storeToXML() to convert properties values into an XML file.

1. Convert properties values to XML file
The below example creates some property values and stores them as an XML file.
PropertiesToXml.java
package com.mkyong.xml.tips;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.nio.charset.StandardCharsets;
import java.util.Properties;
public class PropertiesToXml {
public static void main(String[] args) throws IOException {
// create some properties values on demand
Properties props = new Properties();
props.setProperty("email.support", "[email protected]");
props.setProperty("http.port", "8080");
props.setProperty("http.server", "localhost");
try (OutputStream output =
new FileOutputStream("c:\\test\\server-config.xml")) {
// convert the properties to an XML file
props.storeToXML(output, "Server config file", StandardCharsets.UTF_8);
}
}
}
Output
c:\\test\\server-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
<comment>Server config file</comment>
<entry key="http.port">8080</entry>
<entry key="email.support">[email protected]</entry>
<entry key="http.server">localhost</entry>
</properties>
2. Convert a properties file to an XML file
The below example loads a .properties file and stores them as an XML file.
application.properties
greeting.message=hello
quarkus.http.port=8080
PropertiesToXml2.java
package com.mkyong.xml.tips;
import java.io.*;
import java.nio.charset.StandardCharsets;
import java.util.Properties;
public class PropertiesToXml2 {
public static void main(String[] args) throws IOException {
Properties props = new Properties();
try (InputStream input =
new FileInputStream("src/main/resources/application.properties")) {
// loads a properties file
props.load(input);
}
try (OutputStream output =
new FileOutputStream("c:\\test\\server-config.xml")) {
// convert the properties to an XML file
props.storeToXML(output, "Server config file",
StandardCharsets.UTF_8);
}
}
}
Output
c:\\test\\server-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
<comment>Server config file</comment>
<entry key="greeting.message">hello</entry>
<entry key="quarkus.http.port">8080</entry>
</properties>
