I beat the P4 in to a semblance of modern XML. Not perfect AT ALL, but it's consistent and it validates.

I also downloaded the same file from Pelagios, which has all places marked up with recogito and pleiades ids. I'll need to merge the two files at some point.

XPATH to get the bits already marked up in Perseus version
Places (879): distinct-values(//name[@type='place']/text())
People (1060): distinct-values(//name[@type='pers']/text())
Groups (629): distinct-values(//name[@type='ethnic']/text())

*note that many (all?) places are marked up twice, wrapping a placeName in a name type="place". There are 245 of the former and 879 of the latter. Groups seem to be of a 'national' type (e.g. Egyptians).
