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

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 necessary cleanup here.
