element. If it is not the case,
getElement(name)

This method is equivalent to getElement(Name)
, except that the name to use
is specified by a string and a separator separating the different elements of
the name.

, the name corresponds to an object
local to the target context.
If the name begins with the separator, the name is an absolute name (this
only makes sense if the context has a tree structure); otherwise, the name is
relative to the target context.
