Format XML generated by Xstream

Question

I want to format the output XML generated by Xstream, to make it more readable. Currently, a newline is added after each element but I would like newline to be added after every attribute. Is there a way to do this?

Pretty Print Writer is used by default to format the output of the xml but this doesn't suffice for me. I want newline to be added after every

Answer 1

XStream includes a PrettyPrintWriter

After building your XStream...

XStream xstream = //...whatever

Instead of:

// p is my object needing xml serialization
xstream.toXML(p)

Use something like this to make it pretty:

BufferedOutputStream stdout = new BufferedOutputStream(System.out);
xstream.marshal(p, new PrettyPrintWriter(new OutputStreamWriter(stdout)));

So, how could I tell it to indent with, say... four spaces? I can't seem to be able to find a method for this? Is this supported? – Spectacles

@Spectacles Use the alternative constructor that takes an indentation chararray, e.g. new PrettyPrintWriter(writer, new char[]{' ', ' ', ' ', ' '}) – Kaminski

@aetheria: Thanks, I came across exactly that solution myself. – Spectacles

This does not work if you are using the Stax driver. Any other ideas? – Odontograph

Take a look at their tutorial on tweaking the output.

I have seen that tutorial but it didn't help. – Dimercaprol

Thank you @GáborLipták - the link has been fixed – Gusman

Wow. That was fast :D – Psychologist

Answer 3

I've used this to :

        xstream= new XStream(new DomDriver());

But it's not so efficient than StaxDriver()
