NAME

XML::SAX2Perl -- translate Java/CORBA style SAX methods to Perl methods

SYNOPSIS

 use XML::SAX2Perl;

 $sax2perl = XML::SAX2Perl(Handler => $my_handler);
 $sax->setDocumentHandler($sax2perl);

DESCRIPTION

XML::SAX2Perl is a SAX filter that translates Java/CORBA style SAX methods to Perl style method calls. This man page summarizes the specific options, handlers, and properties supported by XML::SAX2Perl; please refer to the Perl SAX standard XML::SAX for general usage information.

METHODS

new

Creates a new parser object. Default options for parsing, described below, are passed as key-value pairs or as a single hash. Options may be changed directly in the parser object unless stated otherwise. Options passed to `parse()' override the default options in the parser object for the duration of the parse.

parse

Parses a document. Options, described below, are passed as key-value pairs or as a single hash. Options passed to `parse()' override default options in the parser object.

location

Returns the location as a hash:

  ColumnNumber    The column number of the parse.
  LineNumber      The line number of the parse.
  PublicId        A string containing the public identifier, or undef
                  if none is available.
  SystemId        A string containing the system identifier, or undef
                  if none is available.
SAX DocumentHandler Methods

The following methods are DocumentHandler methods that the SAX 1.0 parser will call and XML::SAX2Perl will translate to Perl SAX methods calls. See SAX 1.0 for details.

 setDocumentLocator(locator)
 startDocument()
 endDocument()
 startElement(name, atts)
 endElement(name)
 characters(ch, start, length)
 ignorableWhitespace(ch, start, length)
 processingInstruction(target, data)

OPTIONS

The following options are supported by XML::SAX2Perl:

 Handler          default handler to receive events
 DocumentHandler  handler to receive document events
 DTDHandler       handler to receive DTD events
 ErrorHandler     handler to receive error events
 EntityResolver   handler to resolve entities
 Locale           locale to provide localisation for errors
 Source           hash containing the input source for parsing

If no handlers are provided then all events will be silently ignored, except for `fatal_error()' which will cause a `die()' to be called after calling `end_document()'.

If a single string argument is passed to the `parse()' method, it is treated as if a `Source' option was given with a `String' parameter.

The `Source' hash may contain the following parameters:

 ByteStream       The raw byte stream (file handle) containing the
                  document.
 String           A string containing the document.
 SystemId         The system identifier (URI) of the document.
 PublicId         The public identifier.
 Encoding         A string describing the character encoding.

If more than one of `ByteStream', `String', or `SystemId', then preference is given first to `ByteStream', then `String', then `SystemId'.

HANDLERS

The following handlers and properties are supported by XML::SAX2Perl:

DocumentHandler methods

start_document

Receive notification of the beginning of a document.

 Locator          An object that can return the location of any SAX
                  document event.
end_document

Receive notification of the end of a document.

No properties defined.

start_element

Receive notification of the beginning of an element.

 Name             The element type name.
 Attributes       Attributes attached to the element, if any.

ALPHA WARNING: The `Attributes' value is not translated from the SAX 1.0 value, so it will contain an AttributeList object.

end_element

Receive notification of the end of an element.

 Name             The element type name.
characters

Receive notification of character data.

 Data             The characters from the XML document.
ignorable_whitespace

Receive notification of ignorable whitespace in element content.

 Data             The characters from the XML document.
processing_instruction

Receive notification of a processing instruction.

 Target           The processing instruction target. 
 Data             The processing instruction data, if any.
