selenium+phantomjs 无法找到页面元素?

Question

试着爬http://data.futures.hexun.com...用了selenium+phantomjs,但是出了问题.
不管怎么样也找不到想要的标签.
希望各位大神能帮小弟一把.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

url = "http://data.futures.hexun.com/cccj.aspx"
driver = webdriver.PhantomJS(executable_path="phantomjs.exe")
driver.get(url)
try:
    elem = WebDriverWait(driver,10).until(
        EC.presence_of_element_located((By.ID,"sExc1")))
finally:
    elem = driver.find_elements_by_id("sExc1")
    print(len(elem))

报错:
