as always involving tests for empty, it depends what you mean bey empty
//*[@name][(not(node()))]
tests for no element children at all (and a name attribute) so
<a name=""> </a> is non-empty, as is
<a name=""><!-- this --></a>
If you want want white space to count as empty then
//*[@name][not(normalize-space()))]
now the two above are selected (ie counted as empty) but
so is
<a name=""> <b/> </a>
If sub elements may be there you may want somnething like
//*[@name][not(*)][not(normalize-space()))]
