How do I de-serialize an attribute and a text node using XStream?

I would like to de-serialize the following XML using XStream:

<root>
    <node att="value">text</node>
</root>

into a Java object with two fields of type String. How do I do this?

I've seen these questions, but what I need to do is actually the reverse operation.

As hinted in a couple of the serialization examples you found, ToAttributedValueConverter is about the most direct way to do this. It allows you to handle the fields on a class as XML attributes, with one picked out as the XML body.

With these two classes to receive the data:

@XStreamAlias("root")
public class Root {
    private Node node;
}

@XStreamConverter(value = ToAttributedValueConverter.class, strings = {
        "text" })
public class Node {
    private String att;

    private String text;
}

This deserializes correctly:

    XStream xstream = new XStream();
    xstream.processAnnotations(Root.class);

    Root root = (Root) xstream.fromXML(xml);
