you can use \gobbleoneargument here

the next solution may help:

\defineXMLargument [comment] \XMLhideelement

\long\def\XMLhideelement#1%
   {\futurelet\nexttoken\doXMLhideelement}

\def\doXMLhideelement
   {\ifx\nexttoken\blankspace\removeunwantedspaces\fi}

maybe i will add something \defineXMLhide; will think about it
