NAME

       MDOM::Token::Whitespace - Tokens representing ordinary white space

INHERITANCE

         MDOM::Token::Whitespace
         isa MDOM::Token
             isa MDOM::Element

DESCRIPTION

       As a full "round-trip" parser, MDOM records every last byte in a file and ensure that it
       is included in the MDOM::Document object.

       This even includes whitespace. In fact, Perl documents are seen as "floating in a sea of
       whitespace", and thus any document will contain vast quantities of
       "MDOM::Token::Whitespace" objects.

       For the most part, you shouldn't notice them. Or at least, you shouldn't have to notice
       them.

       This means doing things like consistently using the "S for significant" series of
       MDOM::Node and MDOM::Element methods to do things.

       If you want the nth child element, you should be using "schild" rather than "child", and
       likewise "snext_sibling", "sprevious_sibling", and so on and so forth.

METHODS

       Again, for the most part you should really not need to do anything very significant with
       whitespace.

       But there are a couple of convenience methods provided, beyond those provided by the
       parent MDOM::Token and MDOM::Element classes.

   null
       Because MDOM sees documents as sitting on a sort of substrate made of whitespace, there
       are a couple of corner cases that get particularly nasty if they don't find whitespace in
       certain places.

       Imagine walking down the beach to go into the ocean, and then quite unexpectedly falling
       off the side of the planet. Well it's somewhat equivalent to that, including the whole
       screaming death bit.

       The "null" method is a convenience provided to get some internals out of some of these
       corner cases.

       Specifically it create a whitespace token that represents nothing, or at least the null
       string ''. It's a handy way to have some "whitespace" right where you need it, without
       having to have any actual characters.

   tidy
       "tidy" is a convenience method for removing unneeded whitespace.

       Specifically, it removes any whitespace from the end of a line.

       Note that this doesn't include POD, where you may well need to keep certain types of
       whitespace. The entire POD chunk lives in its own MDOM::Token::Pod object.
