java.lang.Objectcom.saxonica.jaxp.ValidatingReader
public class ValidatingReader
This class is a Saxon implementation of XMLReader that performs schema validation using Saxon's schema processor.
This class is supplied for the benefit of applications that expect to perform validation by creating a validating SAX parser; it allows such applications to take advantage of the Saxon validator with no change to the application.
| Constructor Summary | |

ValidatingReader()

|
ValidatingReader(EnterpriseConfiguration config)
Create a ValidatingReader that uses a specified Saxon Configuration. |
|
ValidatingReader(EnterpriseConfiguration config,
XMLReader parser)

Saxon accepts the Apache-defined properties
http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation and
http://apache.org/xml/properties/schema/external-schemaLocation to define the
location of schema documents. These properties may be set repeatedly to load more than one
schema document.
To enable schema validation using XSD 1.1, the property FeatureKeys.XSD_VERSION
must be set to the value "1.1".

SAXNotRecognizedException - if the property name is not recognized, or if the value is inappropriate
SAXNotSupportedExceptionpublic void setEntityResolver(EntityResolver resolver)
If the application does not register an entity resolver, the XMLReader will perform its own default resolution.
Applications may register a new or different resolver in the middle of a parse, and the SAX parser must begin using the new resolver immediately.

If the application does not register an error handler, all error events reported by the SAX parser will be silently ignored; however, normal processing may not continue. It is highly recommended that all SAX applications implement an error handler to avoid unexpected bugs.
Applications may register a new or different handler in the middle of a parse, and the SAX parser must begin using the new handler immediately.

public void parse(InputSource input)
throws IOException,
SAXException
The application can use this method to instruct the XML reader to begin parsing an XML document from any valid input source (a character stream, a byte stream, or a URI).
Applications may not invoke this method while a parse is in progress (they should create a new XMLReader instead for each nested XML document). Once a parse is complete, an application may reuse the same XMLReader object, possibly with a different input source. Configuration of the XMLReader object (such as handler bindings and values established for feature flags and properties) is unchanged by completion of a parse, unless the definition of that aspect of the configuration explicitly specifies other behavior. (For example, feature flags or properties exposing characteristics of the document being parsed.)
During the parse, the XMLReader will provide information about the XML document through the registered event handlers.
This method is synchronous: it will not return until parsing has ended. If a client application wants to terminate parsing early, it should throw an exception.

SAXException - Any SAX exception, possibly
wrapping another exception.

public void parse(String systemId)
throws IOException,
SAXException
This method is a shortcut for the common case of reading a document from a system identifier. It is the exact equivalent of the following:
parse(new InputSource(systemId));
If the system identifier is a URL, it must be fully resolved by the application before it is passed to the parser.

SAXException - Any SAX exception, possibly
wrapping another exception.
IOException - An IO exception from the parser,
