[SHRINKDESC-125] XML representation for toString()

[rbattenfeld]

Hi Andrew

I have implemented a NodeExporter very similar to the existing NodeImporter SPI. There is no redundant code which exports a Descriptor or a node. Let me know if you wish changes.

Regards,
Ralf

I'm not quite understanding the issue...looks like this is already covered:

https://github.com/shrinkwrap/descriptors/blob/master/api-base/src/main/java/org/jboss/shrinkwrap/descriptor/api/Descriptor.java#L42

Also, this patch has the Exporter API and SPI accepting the Node to be exported, when presumably this would just be a class member anyway?

In any case, I've added a commit to trim out some copy/paste artifacts in my own fork of SHRINKDESC-125. Let's see what Jesper says regarding my comment on the issue (I think all the support he needs is already in place).

That said, I would like to supply a "toString()" method which accepts a Formatter, such that we can format in a variety of ways (this is already provided for in ShrinkWrap archives, for example).

My understanding was that he wants to export an individual sub node into an XML string, not just the whole descriptor instance. Feel free to change whatever is needed. I learned a little bit about SPI layer:-)

Cool, thanks. I've asked Jesper to comment on the issue.
