the InElement() and [Add|Close]HtmlEnvironment() family of
functions to add, remove, and search against HTML tag attributes
for all recently stacked HTML tag environments. Previously, tag
attributes were not retained; they were simply returned as text
from the AddHtmlEnvironment() function. Markup modules producing
complex HTML -- particularly, complex HTML having deeply nested
span or div tags -- can leverage the newly rewritten functions,
below, to simplify, streamline, and "clean up" their markup code.
(InElement): Rewritten to use this new variable.
(AddHtmlEnvironment): Rewritten to use this new variable.
(CloseHtmlEnvironment): Rewritten to use this new variable.
(CloseHtmlEnvironments): Rewritten to use this new variable.
(CloseHtmlEnvironmentUntil): Rewritten to use this new variable.
(AddOrCloseHtmlEnvironment): New function. Added so as to avoid
duplicate redefinition in the Creole, Creole Addition, and Usemod
modules.
* modules/usemod.pl (UsemodRule): Corrected erroneous usage of the
InElement() function. (I don't think UsemodRule() was ever quite
right, really; it's a bit surprising it worked this long!)
