From manual page:

Documentation needs some more information, to clarify when simplexml object is considered true.

More information here:

Tried adding it to documentation
    <literal>SimpleXML</literal> evaluates to &true; only if it has child nodes or properties - only then object is not considered empty.
    To check if <literal>SimpleXML</literal> object has &string; value you have to cast it to &string;

I agree that the wording of the documentation is unfortunate:

| SimpleXML objects created from empty tags

An empty tag would most likely be something like <>. Speaking of
empty elements would be better, but would not take into account
that an empty element may have attributes (not properties), and in
this case casting the respective SimpleXML to bool would also
yield true.
