Constructor Detail

DOMParser

public DOMParser(org.apache.xerces.xni.parser.XMLParserConfiguration config)

Constructs a DOM parser using the specified parser configuration.

DOMParser

public DOMParser()

Constructs a DOM parser using the dtd/xml schema parser configuration.

DOMParser

public DOMParser(SymbolTable symbolTable)

Constructs a DOM parser using the specified symbol table.

DOMParser

public DOMParser(SymbolTable symbolTable,
         org.apache.xerces.xni.grammars.XMLGrammarPool grammarPool)

Constructs a DOM parser using the specified symbol table and 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,
              boolean state)
                throws org.xml.sax.SAXNotRecognizedException,
                       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 - If the requested feature is not known.

org.xml.sax.SAXNotSupportedException - If the requested feature is known, but the requested state is not supported.

getFeature

public boolean getFeature(java.lang.String featureId)
                   throws org.xml.sax.SAXNotRecognizedException,
                          org.xml.sax.SAXNotSupportedException

Query the state of a feature. Query the current state of any feature in a SAX2 parser. The parser might not recognize the feature.

Parameters:

featureId - The unique identifier (URI) of the feature being set.

Returns:

The current state of the feature.

Throws:

org.xml.sax.SAXNotRecognizedException - If the requested feature is not known.

org.xml.sax.SAXNotSupportedException - If the requested feature is known but not supported.

setProperty

public void setProperty(java.lang.String propertyId,
               java.lang.Object value)
                 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.SAXNotRecognizedException - If the requested property is not known.

org.xml.sax.SAXNotSupportedException - If the requested property is known, but the requested value is not supported.

getProperty

public java.lang.Object getProperty(java.lang.String propertyId)
                             throws org.xml.sax.SAXNotRecognizedException,
                                    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.

Parameters:

propertyId - The unique identifier (URI) of the property being set.

Returns:

The current value of the property.

Throws:

org.xml.sax.SAXNotRecognizedException - If the requested property is not known.

org.xml.sax.SAXNotSupportedException - If the requested property is known but not supported.

getXMLParserConfiguration

public org.apache.xerces.xni.parser.XMLParserConfiguration getXMLParserConfiguration()

Returns this parser's XMLParserConfiguration.
