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 %_ variable 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.
