XML::SAX2Perl -- translate Java/CORBA style SAX methods to Perl methods
use XML::SAX2Perl;
$sax2perl = XML::SAX2Perl(Handler => $my_handler);
$sax->setDocumentHandler($sax2perl);
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.
- 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)
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'.
The following handlers and properties are supported by
XML::SAX2Perl:
- 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.
