If this is not what you want, change your canConvert method to return true only if class equals GregorianCalendar.

If the implementation of Birthday ensures, that none of its fields could hold a null value and gender contains a valid value, then we could drop the null condition in the marshal method and in unmarshal we could omit the loop as well as the comparison of the tag names:. From the XStream documentation:.

While XStream is capable of converting this class without any problem, we write our own custom converter just for demonstration. This is not allowed. Take a look at this question: Note, that in implementation of a SingleValueConverter is required thouggtworks attributes, since these objects have to be represented by a single string only. But even nicer, our XML is also simplified using the alias for the Person class. I xm, trying to deserialize a string in Java using the Domriver package.


We use the moveDown and moveUp methods to move in the tree hierarchy, so we thoughtworke simply moveDownread the value and moveUp. Can anyone shed some light on these exceptions? This worked for me. You might want to take a look at registering aliases: Since the String representation is complete, a nested element is not necessary anymore:.

This is an encoding issue.

I will look more into this option. Now we can output the data It is just a root node and about 25 child nodes of varying data types byte array, string, int, boolean.

This time we want to reuse our already written converters for the Person and the Calendar and add an own attribute for the gender. The XML string is actually being encoded in Cso there really in no comparison i can make there.

And the other way around I get the XML cannot change format of XML from a server and try to save its node information to the corresponding variables in a certain class. I removed the junk characters on my end making sure the string “startsWith” the correct xml header. But we reuse the converters registered in XStream for our member fields and handle null values:.


Our converter will receive the Locale in its constructor and we will keep a reference to it in a member variable:.

You work on a stream and accessing the value of a tag or its members will close the surrounding tag that is still active when the method is called. Ok so you simply need to make sure that content gets removed before you attempt to deserialize it. Brian Agnew k 31 Now that we have configured a simple class to play with, let’s see what XStream converters can do for us I think you may have a lot of work ahead of you depending on the XML you have to deserialise.

Try using an attribute called fullname in the person tag instead of creating a new child node.

Let’s enhance the Person with a String representation, that contains all necessary text to recreate the instance:. Now we tell whoever calls us that we can handle only Person’s and nothing else, including those classes which extends Person.
