Hi John,
I send you a sample test code that works correctly.
I hope it will help you. Otherwise, could you send us a reproductible
test code?
Best regards,
Thierry Boileau

Hey, again, all.
I'm trying to use an XPath expression to get a NodeSet. This ought to be
really straightforward, based on the sample code I've seen, but I'm
having some troubles. I've verified that my response contains a valid
XHTML entity.
DomRepresentation doc = response.getEntityAsDom();
String xpath = "//a";
NodeSet nodes = doc.getNodes(xpath); //This returns null
I've traced in enough to see that the InputStream inside the
DomRepresentation is null - XmlRepresentation.internalEval() is catching
the InvalidArgumentException that gets thrown by DocumentBuildre.parse().
Is there some step I'm missing here?
Thanks for any help!
(I'm running Restlet 1.1 RC1, JDK 1.6.0_06, in Eclipse 3.3.2, on Windows
Vista.)
