[Xmlunit-general] temporary extension for xsd validating

[Luca Dall'O. <lda...@un...>]

I have really appreciated your enhancement to the Validator class 
including the useXMLSchema() method; now I can validate my xml using xsd 
schema.
Still, I couldn't find out how to redirect the retrival of xsd files : 
they are always supposed to be in the project home directory (or the ant 
home, depending on the build tool I use).
After some code digging I suppose that the current way to redirect files 
  works only for DTDs, so I tried to extend it for xsd too.
I have not written a clean solution but it seems to work, so I thought 
better to post it : perhaps it could be useful for others too.
My solution is based on an extension of the DoctypeReader class (this 
way I can pass it to the Validator constructor) that parses the input, 
adds a couple of attributes to the root element with the xsd info and 
serializes it back to a string... very similar to the doctypeReader 
itself. I have written a simple helper class to use the assertXMLValid() 
  interface, it can be useful as an example of the calling.
This is the way I call it :

     private String xsdName = "ordinativoFirmato.xsd";
     private String xsdPath = 
this.getClass().getResource(xsdName).toString();

	...

         MyXMLAssert.assertXMLValid(supposedNormalizedString, xsdName, 
xsdPath);

I think that a much cleaner way to solve this problem would be to make 
use of oasis catalogs :

An implementation can be downloaded at the apache site in the xml 
commons package, and IMVHO it should be rather straightforward to add it 
to xmlunit:

If you are interested I can have a look at it, just let me know!
