[jdom-interest] JDOM in memory schema validation

[Alessandro Kohler]

Hi Jason (or anyone who has the answer:-),
regarding what you wrote some time ago (april 1st I think it was) ..

>turned on is NOT good enough because it only checks the doc against the

I validate incoming xml data against a schema of my choice by setting features
and properties in the parser (I use xerces with a custom content handler to
generate jdom documents representing sections of the incoming xml) and I believe
one can set the same features and properties also when using jdom's builder.

does what you say mean that if the xml I receive declares a schema within the
document, the parser would rather validate against that schema than using mine?

I haven't tried it out, but I guess I could have a little problem here if that
is the case ... :-)

thanks for your any hint
alessandro
