A bit rusty but here's a script to parse a collection of KML files and pull out all the interesting data

app.py

from xml.dom.minidom import parse

def get_label(node):
    name = node.getElementsByTagName('name')[0]
    label = name.firstChild.nodeValue
    return label

def get_coords(node):
    coordinates = node.getElementsByTagName('coordinates')[0]
    coords = coordinates.firstChild.nodeValue
    split = coords.split(" ")
    return split

def parse_file(f):
    dom = parse(f)

    for node in dom.getElementsByTagName('Placemark'):
        label = get_label(node)
        split = get_coords(node)
        count = len(split)

        if (count > 1):
            print '{0} has {1} nodes'.format(label,count)
    print '\n'


from os import listdir, path
current_dir = '.'
kml_files = [ f for f in listdir(current_dir) if path.splitext(f)[1] == '.kml' ]

for f in kml_files:
    print 'Opening file {0}'.format(f)
    parse_file(f)
