XML::Parser::Style::Stream − Stream style for XML::Parser


  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
    }
  }

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.
