This seems to do it...(at the moment...)

def getcnnvalue(market, cnnpage):
    marketstart = cnnpage.find("<!--MARKETSTART: %s -->" % market)
    datatag = '<td class="chartdata">'
    chartdata = cnnpage[marketstart:].find(datatag) + len(datatag) +
marketstart
    value = cnnpage[chartdata:chartdata +
cnnpage[chartdata:].find(' ')]
    return value



print '\n\n', getcnnvalue('sandp', cnnpage)

print '\n\n', getcnnvalue('nasdaq', cnnpage)
