NAME

       XML::Parser::Style::Subs - glue for handling element callbacks

SYNOPSIS

	 use XML::Parser;
	 my $p = XML::Parser->new(Style => 'Subs', Pkg => 'MySubs');
	 $p->parsefile('foo.xml');

	 {
	   package MySubs;

	   sub foo {
	     # start of foo tag
	   }

	   sub foo_ {
	     # end of foo tag
	   }
	 }

DESCRIPTION

       Each time an element starts, a sub by that name in the package specified by the Pkg option is called with the same parameters that the
       Start handler gets called with.

       Each time an element ends, a sub with that name appended with an underscore ("_"), is called with the same parameters that the End handler
       gets called with.

       Nothing special is returned by parse.

NAME

       XML::Parser::Style::Stream - Stream style for XML::Parser

SYNOPSIS

	 use XML::Parser;
	 my $p = XML::Parser->new(Style => 'Stream', Pkg => 'MySubs');
	 $p->parsefile('foo.xml');

	 {
	   package MySubs;

	   sub StartTag {
	     my ($e, $name) = @_;
	     # do something with start tags
	   }

	   sub EndTag {
	     my ($e, $name) = @_;
	     # do something with end tags
	   }

	   sub Characters {
	     my ($e, $data) = @_;
	     # do something with text nodes
	   }
	 }

DESCRIPTION

       This style uses the Pkg option to find subs in a given package to call for each event.  If none of the subs that this style looks for is
       there, then the effect of parsing with this style is to print a canonical copy of the document without comments or declarations.  All the
       subs receive as their 1st parameter the Expat instance for the document they're parsing.

       It looks for the following routines:

       * StartDocument
	   Called at the start of the parse .

       * StartTag
	   Called for every start tag with a second parameter of the element type. The $_ variable will contain a copy of the tag and the %_ vari-
	   able will contain attribute values supplied for that element.

       * EndTag
	   Called for every end tag with a second parameter of the element type. The $_ variable will contain a copy of the end tag.

       * Text
	   Called just before start or end tags with accumulated non-markup text in the $_ variable.

       * PI
	   Called for processing instructions. The $_ variable will contain a copy of the PI and the target and data are sent as 2nd and 3rd
	   parameters respectively.

       * EndDocument
	   Called at conclusion of the parse.
