I think that, your XPath expression should be following,

//p[o:p eq '&#160;'][count(following-sibling::*[name() eq 'p'][o:p eq
'&#160;']) ge 10][1]

(not tested)

The predicate [position() le 10] occurring for the first time in your
expression, doesn't seem to be needed.

I could visually inspect / review Mike Kay's expression, and can say that
its correct.
