Looks ok, but "UML!Class" means this context works only for UML!Class,
you want element.("UML!Element")
Because in the matching phase your guard "c.hasStereotype('Process')"
will be testes with all elements and not all of them are "UML!Class".
If you stick to your helper your guard should be :
"
(
if u.oclIsTypeOf(UML!"uml::Activity") and
 			c.oclIsTypeOf(UML!"uml::Class") then  						c.name='onlinesale' and
 			c.hasStereotype('Process')
			else
			false
			endif
> 			)
