Hi Sankar, how the arguments can be used while passing through SAXException, this you can learn very well in Java tutorials provided by sun java. Below are the link helpful to you these will describe you how to use arguments and also other help that might be useful for you. 1)This package provides the core SAX APIs. 2)This package contains interfaces to SAX2 facilities that conformant SAX drivers won't necessarily support.

3)This package contains 'helper' classes, including support for bootstrapping SAX-based applications. Hope this may solve your problem Thanks sandeep Sharma PS: if helpful please reward points 0 Likes 0.

— Interface for XML parsers Source code: SAX parsers implement the interface. They are implemented in a Python module, which must provide a function createparser.

This function is invoked by with no arguments to create a new parser object. Class xml.sax.xmlreader. XMLReader Base class which can be inherited by SAX parsers. Class xml.sax.xmlreader. IncrementalParser In some cases, it is desirable not to parse an input source at once, but to feed chunks of the document as they get available. Note that the reader will normally not read the entire file, but read it in chunks as well; still parse won’t return until the entire document is processed. So these interfaces should be used if the blocking behaviour of parse is not desirable.

When the parser is instantiated it is ready to begin accepting data from the feed method immediately. After parsing has been finished with a call to close the reset method must be called to make the parser ready to accept new data, either from feed or using the parse method. Note that these methods must not be called during parsing, that is, after parse has been called and before it returns.

By default, the class also implements the parse method of the XMLReader interface using the feed, close and reset methods of the IncrementalParser interface as a convenience to SAX 2.0 driver writers. Class xml.sax.xmlreader. Locator Interface for associating a SAX event with a document location. A locator object will return valid results only during calls to DocumentHandler methods; at any other time, the results are unpredictable. If information is not available, methods may return None.

Class xml.sax.xmlreader. InputSource ( systemid=None ) Encapsulation of the information needed by the to read entities. This class may include information about the public identifier, system identifier, byte stream (possibly with character encoding information) and/or the character stream of an entity. Applications will create objects of this class for use in the method and for returning from EntityResolver.resolveEntity. An belongs to the application, the is not allowed to modify objects passed to it from the application, although it may make copies and modify those. Class xml.sax.xmlreader.

AttributesImpl ( attrs ) This is an implementation of the Attributes interface (see section ). This is a dictionary-like object which represents the element attributes in a startElement call. In addition to the most useful dictionary operations, it supports a number of other methods as described by the interface. Objects of this class should be instantiated by readers; attrs must be a dictionary-like object containing a mapping from attribute names to attribute values. Class xml.sax.xmlreader.

AttributesNSImpl ( attrs, qnames ) Namespace-aware variant of, which will be passed to startElementNS. It is derived from, but understands attribute names as two-tuples of namespaceURI and localname. In addition, it provides a number of methods expecting qualified names as they appear in the original document. This class implements the AttributesNS interface (see section ). Changed in version 3.5: Added support of character streams. GetContentHandler ( ) Return the current. SetContentHandler ( handler ) Set the current.

If no is set, content events will be discarded. GetDTDHandler ( ) Return the current.

SetDTDHandler ( handler ) Set the current. If no is set, DTD events will be discarded. GetEntityResolver ( ) Return the current.

SetEntityResolver ( handler ) Set the current. If no is set, attempts to resolve an external entity will result in opening the system identifier for the entity, and fail if it is not available. GetErrorHandler ( ) Return the current.

SetErrorHandler ( handler ) Set the current error handler. If no is set, errors will be raised as exceptions, and warnings will be printed. SetLocale ( locale ) Allow an application to set the locale for errors and warnings. SAX parsers are not required to provide localization for errors and warnings; if they cannot support the requested locale, however, they must raise a SAX exception.

Applications may request a locale change in the middle of a parse. GetFeature ( featurename ) Return the current setting for feature featurename. If the feature is not recognized, SAXNotRecognizedException is raised. The well-known featurenames are listed in the module.

SetFeature ( featurename, value ) Set the featurename to value. If the feature is not recognized, SAXNotRecognizedException is raised. If the feature or its setting is not supported by the parser, SAXNotSupportedException is raised. GetProperty ( propertyname ) Return the current setting for property propertyname.

If the property is not recognized, a SAXNotRecognizedException is raised. The well-known propertynames are listed in the module. SetProperty ( propertyname, value ) Set the propertyname to value. If the property is not recognized, SAXNotRecognizedException is raised. If the property or its setting is not supported by the parser, SAXNotSupportedException is raised. IncrementalParser Objects Instances of offer the following additional methods: IncrementalParser. Feed ( data ) Process a chunk of data.

Close ( ) Assume the end of the document. That will check well-formedness conditions that can be checked only at the end, invoke handlers, and may clean up resources allocated during parsing. Reset ( ) This method is called after close has been called to reset the parser so that it is ready to parse new documents. The results of calling parse or feed after close without calling reset are undefined. InputSource Objects InputSource.

SetPublicId ( id ) Sets the public identifier of this. GetPublicId ( ) Returns the public identifier of this. SetSystemId ( id ) Sets the system identifier of this. GetSystemId ( ) Returns the system identifier of this. SetEncoding ( encoding ) Sets the character encoding of this. The encoding must be a string acceptable for an XML encoding declaration (see section 4.3.3 of the XML recommendation). The encoding attribute of the is ignored if the also contains a character stream.

GetEncoding ( ) Get the character encoding of this InputSource. SetByteStream ( bytefile ) Set the byte stream (a ) for this input source. The SAX parser will ignore this if there is also a character stream specified, but it will use a byte stream in preference to opening a URI connection itself. If the application knows the character encoding of the byte stream, it should set it with the setEncoding method. GetByteStream ( ) Get the byte stream for this input source.

The getEncoding method will return the character encoding for this byte stream, or None if unknown. SetCharacterStream ( charfile ) Set the character stream (a ) for this input source. If there is a character stream specified, the SAX parser will ignore any byte stream and will not attempt to open a URI connection to the system identifier. GetCharacterStream ( ) Get the character stream for this input source. The AttributesNS Interface This interface is a subtype of the Attributes interface (see section ).

All methods supported by that interface are also available on AttributesNS objects. The following methods are also available: AttributesNS. GetValueByQName ( name ) Return the value for a qualified name. GetNameByQName ( name ) Return the (namespace, localname) pair for a qualified name. GetQNameByName ( name ) Return the qualified name for a (namespace, localname) pair. GetQNames ( ) Return the qualified names of all attributes.
