Ok so you simply need to make sure that content gets removed before you attempt to deserialize it. You might want to take a look at registering aliases: Email Required, but never shown. While XStream is capable of converting this class without any problem, we write our own custom converter just for demonstration. Sign up using Email and Password. This is not allowed.

It may be worth posting the XML you have to deserialise. Assaf Israel 2 9. Now that we have configured a simple class to play with, let’s see what XStream converters can do for romdriver Brian Agnew k 31 thoughtwoeks 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:.
I believe they are using the XmlSerializer class provided by. This worked for me.
XStream – Converter Tutorial
I am trying to deserialize a string in Java using the XStream package. From the XStream documentation: John Saunders k 22 I think you may have a lot of work ahead of you depending on the XML you have to deserialise.
Domdruver go for converting a Calendar in a localized string If this is not what you want, xxstream your canConvert method to return true only if class equals GregorianCalendar. Now that we know how the Converter interface works, let’s create a simple calendar converter which uses the locale to convert the information.
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 XStream package can serialize my class fine.
I believe this has to do with XStream not knowing what classes to match up with certain XML elements based on their name. But we reuse the converters registered in XStream for our member fields and handle null values:. And the other way around Now we tell whoever calls us that we can handle only Person’s and nothing else, including those classes which extends Person.
Since the String representation is complete, a nested element is not necessary anymore:. But even nicer, our XML is also simplified using the alias for the Person class. Note, that in implementation of a SingleValueConverter is required for attributes, since domdrived objects have to be represented by a single string only.
