XML::SAX::ExpatXS(3pm)

NAME
XML::SAX::ExpatXS - Perl SAX 2 XS extension to Expat parser

SYNOPSIS
 use XML::SAX::ExpatXS;

 $handler = MyHandler->new();
 $parser = XML::SAX::ExpatXS->new( Handler => $handler );
 $parser->parse_uri($uri);
  #or
 $parser->parse_string($xml);

DESCRIPTION
XML::SAX::ExpatXS is a direct XS extension to Expat XML parser. It implements Perl SAX 2.1 interface. See http://perl-xml.sourceforge.net/perl-sax/ for Perl SAX API description. Any deviations from the Perl SAX 2.1 specification are considered as bugs.

  Features
The parser behavior can be changed by setting features.

 $parser->set_feature(FEATURE, VALUE);

XML::SAX::ExpatXS provides these adjustable features:

"http://xmlns.perl.org/sax/join-character-data"
    Consequent character data are joined (1, default) or not (0).

"http://xmlns.perl.org/sax/ns-attributes"
    Namespace attributes are reported as common attributes (1, default) or not (0).

"http://xmlns.perl.org/sax/xmlns-uris"
    When set on, xmlns and xmlns:* attributes are put into namespaces in a Perl SAX traditional way; xmlns attributes are in no namespace while xmlns:* attributes are in the "http://www.w3.org/2000/xmlns/" namespace. This feature is set to 1 by default.

"http://xml.org/sax/features/xmlns-uris"
    This feature applies if and only if the "http://xmlns.perl.org/sax/xmlns-uris" feature is off. Then, xmlns and xmlns:* attributes are both put into no namespace (0, default) or into "http://www.w3.org/2000/xmlns/" namespace (1).

"http://xmlns.perl.org/sax/locator"
    The document locator is updated (1, default) for ContentHadler events or not (0).

"http://xmlns.perl.org/sax/recstring"
    A recognized string (the text string currently processed by this XML parser) is either maintained as $parser->{ParseOptions}{RecognizedString} (1) or not (0, default).

"http://xml.org/sax/features/external-general-entities"
    Controls whether this parser processes external general entities (1, default) or not (0).

"http://xml.org/sax/features/external-parameter-entities"
    Controls whether this parser processes external parameter entities including an external DTD subset (1) or not (0, default).

  Constructor Options
Apart from features, the behavior of this parser can also be changed with options to the constructor.

ParseParamEnt
     ParseParamEnt => 1

    This option meaning is exactly the same as the "http://xml.org/sax/features/external-parameter-entities" feature. The option is supported only because of the compatibility with older versions of this module. Turned off by default.

NoExpand
     NoExpand => 1

    No internal entities are expanded if this option is turned on. Turned off by default.

  Read-only Properties

ExpatVersion
    This property returns a version of linked Expat library, for example expat_1.95.7.
