xstream fromxml

`XStream` is a Java library that allows you to serialize Java objects to XML and deserialize XML back to Java objects. It provides a simple API for converting object hierarchies to XML and vice versa.

To deserialize XML to an object using XStream, you can use the `fromXML` method. Here's an example:

import com.thoughtworks.xstream.XStream;

public class Main {
    public static void main(String[] args) {
        // Create an instance of XStream
        XStream xstream = new XStream();

        // Deserialize XML to an object
        String xml = "<person><name>John Doe</name><age>30</age></person>";
        Person person = (Person) xstream.fromXML(xml);

        // Print the deserialized object
        System.out.println(person.getName()); // Output: John Doe
        System.out.println(person.getAge()); // Output: 30
    }
}

class Person {
    private String name;
    private int age;

    // Getters and setters

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

In this example, we create an instance of `XStream` and then use the `fromXML` method to deserialize the XML string to a `Person` object. Finally, we access the properties of the deserialized object.

Note that you need to have the XStream library in your classpath to use it in your project. You can add it as a dependency using a build tool like Maven or Gradle.
