NAME

XML::Parser::LiteCopy - Lightweight regexp-based XML parser

CONTENTS

SYNOPSIS



  use XML::Parser::LiteCopy;

  $p1 = new XML::Parser::LiteCopy;
  $p1->setHandlers(
    Start => sub { shift; print "start: @_\n" },
    Char => sub { shift; print "char: @_\n" },
    End => sub { shift; print "end: @_\n" },
  );
  $p1->parse(<foo id="me">Hello World!</foo>);

  $p2 = new XML::Parser::LiteCopy
    Handlers => {
      Start => sub { shift; print "start: @_\n" },
      Char => sub { shift; print "char: @_\n" },
      End => sub { shift; print "end: @_\n" },
    }
  ;
  $p2->parse(<foo id="me">Hello <bar>cruel</bar> World!</foo>);



DESCRIPTION

This Perl implements an XML parser with a interface similar to XML::Parser. Though not all callbacks are supported, you should be able to use it in the same way you use XML::Parser. Due to using experimantal regexp features it’ll work only on Perl 5.6 and above and may behave differently on different platforms.

Note that you cannot use regular expressions or split in callbacks. This is due to a limitation of perl’s regular expression implementation (which is not re-entrant).

SUBROUTINES/METHODS

    new

Constructor.

As (almost) all SOAP::Lite constructors, new() returns the object called on when called as object method. This means that the following effectifely is a no-op if $obj is a object:



 $obj = $obj->new();



New accepts a single named parameter, Handlers with a hash ref as value:



 my $parser = XML::Parser::Lite->new(
    Handlers => {
        Start => sub { shift; print "start: @_\n" },
        Char => sub { shift; print "char: @_\n" },
        End => sub { shift; print "end: @_\n" },
    }
 );



The handlers given will be passed to setHandlers.

    setHandlers

Sets (or resets) the parsing handlers. Accepts a hash with the handler names and handler code references as parameters. Passing undef instead of a code reference replaces the handler by a no-op.

The following handlers can be set:



 Init
 Start
 Char
 End
 Final
 CData
 Doctype
 Comment
 PI



All other handlers are ignored.

Calling setHandlers without parameters resets all handlers to no-ops.

    parse

Parses the XML given. In contrast to XML::Parser’s parse method, parse() only parses strings.

Handler methods

    Init

Called before parsing starts. You should perform any necessary initializations in Init.

    Start

Called at the start of each XML node. See XML::Parser for details.

    Char

Called for each character sequence. May be called multiple times for the characters contained in an XML node (even for every single character). Your implementation has to make sure that it captures all characters.

    End

Called at the end of each XML node. See XML::Parser for details

    Comment

See XML::Parser for details

    PI

See XMLDecl in XML::Parser for details, but also includes other processing instructions

    Doctype

See XML::Parser for details

    Final

Called at the end of the parsing process. You should perform any neccessary cleanup here.
