This faq page does not tell how to proceed further. As
in there it says that you get PSVIProvider instance
(by casting SAXParser) but than how do tell after that
which is the document to be parsed. Lets for example
prv. if one uses this code to parse the Document
validated against a schema:
reader =
XMLReaderFactory.createXMLReader(vendorClass);
// register content handler
reader.setContentHandler(contentHandler);
// register error handler
reader.setErrorHandler(errHandler);
// set the corresponding features of the SAX parser
reader.setFeature("http://xml.org/sax/features/namespaces";,
true);
reader.setFeature("http://xml.org/sax/features/namespace-prefixes";,
true);
reader.setFeature("http://xml.org/sax/features/validation";,
true);
reader.setFeature("http://apache.org/xml/features/validation/schema";,
true);
// create input source from xml document
InputSource inputSource = new InputSource(xmlURI);
reader.parse(inputSource);
......
Later for this code if one tries to retrieve Schema
Information than would be using PSVI to get handler to
XSModel. Right? So for this he would have something
similar to:
....
SAXParserFactory factory = new
org.apache.xerces.jaxp.SAXParserFactoryImpl();
factory.setFeature("http://xml.org/sax/features/namespaces";,
true);
factory.setFeature("http://xml.org/sax/features/namespace-prefixes";,
true);
factory.setFeature("http://xml.org/sax/features/validation";,
true);
factory.setFeature("http://apache.org/xml/features/validation/schema";,
true);
SAXParser parser = factory.newSAXParser();
PSVIProvider psvi = (PSVIProvider)parser;
But ones he cast parser to PSVIProvider how to proceed
from here to next stage so that he can specify the
document to be parsed and correspondingly get the
Schema Information too.
Sorry for this niche queries.
