    public class DOMParser
    extends AbstractDOMParser
    This is the main Xerces DOM parser class. It uses the abstract DOM parser with a document scanner, a dtd scanner, and a validator, as well as a grammar pool.

    • Method Detail

      • parse

        public void parse​(java.lang.String systemId)
                   throws org.xml.sax.SAXException,
                          java.io.IOException
        Parses the input source specified by the given system identifier.

        This method is equivalent to the following:

             parse(new InputSource(systemId));
         
        Parameters:
        systemId - The system identifier (URI).
        Throws:
        org.xml.sax.SAXException - Throws exception on SAX error.
        java.io.IOException - Throws exception on i/o error.
      • parse

        public void parse​(org.xml.sax.InputSource inputSource)
                   throws org.xml.sax.SAXException,
                          java.io.IOException
        parse
        Parameters:
        inputSource -
        Throws:
        org.xml.sax.SAXException
        java.io.IOException
      • setEntityResolver

        public void setEntityResolver​(org.xml.sax.EntityResolver resolver)
        Sets the resolver used to resolve external entities. The EntityResolver interface supports resolution of public and system identifiers.
        Parameters:
        resolver - The new entity resolver. Passing a null value will uninstall the currently installed resolver.
      • getEntityResolver

        public org.xml.sax.EntityResolver getEntityResolver()
        Return the current entity resolver.
        Returns:
        The current entity resolver, or null if none has been registered.
        See Also:
        setEntityResolver(org.xml.sax.EntityResolver)
      • setErrorHandler

        public void setErrorHandler​(org.xml.sax.ErrorHandler errorHandler)
        Allow an application to register an error event handler.

        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.

        Parameters:
        errorHandler - The error handler.
        Throws:
        java.lang.NullPointerException - If the handler argument is null.
        See Also:
        getErrorHandler()
      • getErrorHandler

        public org.xml.sax.ErrorHandler getErrorHandler()
        Return the current error handler.
        Returns:
        The current error handler, or null if none has been registered.
        See Also:
        setErrorHandler(org.xml.sax.ErrorHandler)
      • setFeature

        public void setFeature​(java.lang.String featureId,

                               org.xml.sax.SAXNotSupportedException
        Set the state of any feature in a SAX2 parser. The parser might not recognize the feature, and if it does recognize it, it might not be able to fulfill the request.
        Parameters:
        featureId - The unique identifier (URI) of the feature.
        state - The requested state of the feature (true or false).

                         throws org.xml.sax.SAXNotRecognizedException,
                                org.xml.sax.SAXNotSupportedException
        Set the value of any property in a SAX2 parser. The parser might not recognize the property, and if it does recognize it, it might not support the requested value.
        Parameters:
        propertyId - The unique identifier (URI) of the property being set.
        value - The value to which the property is being set.
        Throws:

                                            org.xml.sax.SAXNotSupportedException
        Query the value of a property. Return the current value of a property in a SAX2 parser. The parser might not recognize the property.
