man Pod::Simple::PullParserToken () - Pod::Simple::PullParserToken -- tokens from Pod::Simple::PullParser

NAME

Pod::Simple::PullParserToken -- tokens from Pod::Simple::PullParser

SYNOPSIS

Given a CW$parser that's an object of class Pod::Simple::PullParser (or a subclass)... 

  while(my $token = $parser->get_token) {
    $DEBUG and print "Token: ", $token->dump, "\n";
    if($token->is_start) {
      ...access $token->tagname, $token->attr, etc...


    } elsif($token->is_text) {
      ...access $token->text, $token->text_r, etc...


    } elsif($token->is_end) {
      ...access $token->tagname...


    }
  }

(Also see Pod::Simple::PullParser)

DESCRIPTION

When you do CW$parser->get_token on a Pod::Simple::PullParser, you should get an object of a subclass of Pod::Simple::PullParserToken.

Subclasses will add methods, and will also inherit these methods:

$token->type
This returns the type of the token. This will be either the string start, the string text, or the string end. Once you know what the type of an object is, you then know what subclass it belongs to, and therefore what methods it supports. Yes, you could probably do the same thing with code like CW$token->isa('Pod::Simple::PullParserEndToken'), but that's not so pretty as using just CW$token->type, or even the following shortcuts:
$token->is_start
This is a shortcut for CW$token->type() eq "start"
$token->is_text
This is a shortcut for CW$token->type() eq "text"
$token->is_end
This is a shortcut for CW$token->type() eq "end"
$token->dump
This returns a handy stringified value of this object. This is useful for debugging, as in: 
  while(my $token = $parser->get_token) {
    $DEBUG and print "Token: ", $token->dump, "\n";
    ...
  }
