NAME

Pod::Simple::PullParserTextToken -- text-tokens from Pod::Simple::PullParser

SYNOPSIS

(See Pod::Simple::PullParser)

DESCRIPTION

When you do $parser->get_token on a Pod::Simple::PullParser, you might get an object of this class.

This is a subclass of Pod::Simple::PullParserToken and inherits all its methods, and adds these methods:

$token->text

This returns the text that this token holds. For example, parsing C<foo> will return a C start-token, a text-token, and a C end-token. And if you want to get the ``foo'' out of the text-token, call "$token->text"

$token->text(somestring)

This changes the string that this token holds. You probably won't need to do this.

$token->text_r()

This returns a scalar reference to the string that this token holds. This can be useful if you don't want to memory-copy the potentially large text value (well, as large as a paragraph or a verbatim block) as calling $token->text would do.

Or, if you want to alter the value, you can even do things like this:

  for ( ${  $token->text_r  } ) {  # Aliases it with $_ !!

    s/ The / the /g; # just for example

    if( 'A' eq chr(65) ) {  # (if in an ASCII world)
      tr/\xA0/ /;
      tr/\xAD//d;
    }

    ...or however you want to alter the value...
    (Note that starting with Perl v5.8, you can use, e.g.,

        my $nbsp = chr utf8::unicode_to_native(0xA0);
        s/$nbsp/ /g;

    to handle the above regardless if it's an ASCII world or not)
  }

You're unlikely to ever need to construct an object of this class for yourself, but if you want to, call "Pod::Simple::PullParserTextToken->new( text )"
