Sorry for the late response. The grammar caching/preparsing API is not
finalized yet. But you can try the following:
parser.setProperty
("http://apache.org/xml/properties/internal/grammar-pool";, new
XMLGrammarPoolImpl());
Then you'll be using the default grammar pool implementation, which caches
all schema grammars. That is, after the first time a grammar for a give
namespace is parsed, it'll be stored in the grammar pool, and don't need to
be parsed again.
Of course, you can implement a customized XMLGrammarPool, and pass that to
the parsers.
Note that this property is currently considered "internal", so it's not
guaranteed that it won't change in the future.
Hope this helps,

Subject: RE: xml validation with
schema ERROR

Please respond
to
xerces-j-user
Thanks a lot Vijaya. i managed to compile and run
successfully the java code you sent. works perfect.
my next question is:
schema file for the xml is not defined in the xml file
so i added the property '...external-noName...' in
which i can define the external schema file to
validate. works perfect. now, is it possible to cache
this schema file, so that i dont have to read it all
the time i need to validate xml?? is so then how?
thanks a million once again.
