You appear to have hit an "undocumented restriction" :-) in filePro, 
regarding the apparent-but-not-really nesting of punctuation such as "<" 
within an edit.  (ie: you have a quoted "<" within the "<...>" item.)

If that "undocumented restriction" :-) were eliminated, the following would 
work:

     unhtml   { @ | (!"&"!unhtml2!";"!) | * }
     unhtml2  !amp!<"&"> | !eq!<"="> | !lt!<"<"> | !gt!<">">

Note, too, that your construct:

     {!" "!} @

is redundant, as the "@" will eat all trailing spaces.
