NAME¶
XML::ESISParser - Perl SAX parser using nsgmls
SYNOPSIS¶
use XML::ESISParser; $parser = XML::ESISParser->new( [OPTIONS] ); $result = $parser->parse( [OPTIONS] ); $result = $parser->parse($string);
DESCRIPTION¶
"XML::ESISParser" is a Perl SAX parser using the `nsgmls' command of James Clark's SGML Parser (SP), a validating XML and SGML parser. This man page summarizes the specific options, handlers, and properties supported by "XML::ESISParser"; please refer to the Perl SAX standard in `"SAX.pod"' for general usage information.
"XML::ESISParser" defaults to parsing XML and has an option for parsing SGML.
`"nsgmls"' source, and binaries for some platforms, is available from <http://www.jclark.com/>. `"nsgmls"' is included in both the SP and Jade packages.
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.
OPTIONS¶
The following options are supported by "XML::ESISParser":
Handler default handler to receive events DocumentHandler handler to receive document events DTDHandler handler to receive DTD events ErrorHandler handler to receive error events Source hash containing the input source for parsing IsSGML the document to be parsed is in SGML
If no handlers are provided then all events will be silently ignored.
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.
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::ESISParser":
DocumentHandler methods¶
- start_document
- Receive notification of the beginning of a document.
No properties defined.
- 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 A hash containing the attributes attached to the element, if any. IncludedSubelement This element is an included subelement. Empty This element is declared empty.The `"Attributes"' hash contains only string values. The `"Empty"' flag is not set for an element that merely has no content, it is set only if the DTD declares it empty.
BETA: Attribute values currently do not expand SData entities into entity objects, they are still in the system data notation used by nsgmls (inside `|'). A future version of XML::ESISParser will also convert other types of attributes into their respective objects, currently just their notation or entity names are given.
- 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 document. - record_end
- Receive notification of a record end sequence. XML applications should convert this to a new-line.
- processing_instruction
- Receive notification of a processing instruction.
Target The processing instruction target in XML. Data The processing instruction data, if any. - internal_entity_ref
- Receive notification of a system data (SData) internal entity reference.
Name The name of the internal entity reference. - external_entity_ref
- Receive notification of a external entity reference.
Name The name of the external entity reference. - start_subdoc
- Receive notification of the start of a sub document.
Name The name of the external entity reference. - end_subdoc
- Receive notification of the end of a sub document.
Name The name of the external entity reference. - conforming
- Receive notification that the document just parsed conforms to it's
document type declaration (DTD).
No properties defined.
DTDHandler methods¶
- external_entity_decl
- Receive notification of an external entity declaration.
Name The entity's entity name. Type The entity's type (CDATA, NDATA, etc.) SystemId The entity's system identifier. PublicId The entity's public identifier, if any. GeneratedId Generated system identifiers, if any. - internal_entity_decl
- Receive notification of an internal entity declaration.
Name The entity's entity name. Type The entity's type (CDATA, NDATA, etc.) Value The entity's character value. - notation_decl
- Receive notification of a notation declaration.
Name The notation's name. SystemId The notation's system identifier. PublicId The notation's public identifier, if any. GeneratedId Generated system identifiers, if any. - subdoc_entity_decl
- Receive notification of a subdocument entity declaration.
Name The entity's entity name. SystemId The entity's system identifier. PublicId The entity's public identifier, if any. GeneratedId Generated system identifiers, if any. - external_sgml_entity_decl
- Receive notification of an external SGML-entity declaration.
Name The entity's entity name. SystemId The entity's system identifier. PublicId The entity's public identifier, if any. GeneratedId Generated system identifiers, if any.
