For example, parsing 44 CZ<><foo> will return a C start-token, a text-token, and a C end-token. And 45 if you want to get the "foo" out of the text-token, call C<< $token->text >> 46 47 =item $token->text(I<somestring>) 48 49 This changes the string that this token holds. You probably won't need 50 to do this. 51 52 =item $token->text_r() 53 54 This returns a scalar reference to the string that this token holds. 55 This can be useful if you don't want to memory-copy the potentially 56 large text value (well, as large as a paragraph or a verbatim block) 57 as calling $token->text would do. 58 59 Or, if you want to alter the value, you can even do things like this: 60 61 for ( ${ $token->text_r } ) { # Aliases it with $_ !! 62 63 s/ The / the /g; # just for example 64 65 if( 'A' eq chr(65) ) { # (if in an ASCII world) 66 tr/\xA0/ /; 67 tr/\xAD//d; 68 } 69 70 ...or however you want to alter the value... 71 } 72 73 =back 74 75 You're unlikely to ever need to construct an object of this class for 76 yourself, but if you want to, call 77 C<< 78 Pod::Simple::PullParserTextToken->new( I<text> ) 79 >> 80 81 =head1 SEE ALSO 82 83 L<Pod::Simple::PullParserToken>, L<Pod::Simple>, L<Pod::Simple::Subclassing> 84 85 =head1 COPYRIGHT AND DISCLAIMERS 86 87 Copyright (c) 2002 Sean M.
