This is really cool. I would like to include it in PhpWiki!

There are functions in stdlib.php for linking words:
         LinkExistingWikiWord($wikiword)
         LinkUnknownWikiWord($wikiword)
         LinkURL($url, $linktext)
         LinkImage($url, $alt)

Will these do?

Hmm. It would be bad to make you write filtering code, because that
creates a dependency... when something about the linking scheme changes,
you (or someone) would have to change the site map code as well. But at
the moment I don't see an answer other than refactoring the code somehow.

Perhaps in C style, we could introduce flags to ExtractWikiPageLinks to
return all links, only external, only BumbyText, only brackets, etc. The
function is only called once in any given DB library, so the change
wouldn't be unmanagable.
