NAME ^

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

SYNOPSIS ^

Given a $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 $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 $token->isa('Pod::Simple::PullParserEndToken'), but that's not so pretty as using just $token->type, or even the following shortcuts:

$token->is_start

This is a shortcut for $token->type() eq "start"

$token->is_text

This is a shortcut for $token->type() eq "text"

$token->is_end

This is a shortcut for $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";
    ...
  }
