Yes, this should work. However, I don't know if adjusting the tree

How many elements are there in your tree? Memory use in XML can get very
expensive so combining iterparse with xmlfile would be an alternative. Also, if
you're only interested in duplicate names, use a set rather than a dictionary.
Just a few ten's, so performance isn't an issue for me.
Indeed, I changed the code since I don't actually care about the three
infos, just if that block has already been see or not:
#remove dups
no_dups = []
for row in tree.iter("wpt"):
lat,lon = row.attrib.values()
if lat not in no_dups:
no_dups.append(lat)
else:
row.getparent().remove(row)
