我的xpath语法有什么问题？我尝试筛选的节点是，我的代码是：

div class="cmeTableBlockWrapper cmeContentSection cmeContentGroup"
table id="quotesFuturesProductTable1" 
tr[1:]
   td id="quotesFuturesProductTable1_ZCZ4_last"
   td id="quotesFuturesProductTable1_ZCZ4_change"
   td id="quotesFuturesProductTable1_ZCZ4_priorSettle"

url = "http://www.cmegroup.com/trading/agricultural/grain-and-oilseed/corn.html"

driver = webdriver.Chrome() 

driver.get(url) 

table = driver.find_element_by_xpath('//div[class="cmeTableBlockerWrapper cmeContentSection cmeContentGroup"]/table[@id="quotesFuturesProductTable1"]') 

# or table = driver.find_element_by_xpath('//td[contains(div[@class="fixedpage_heading"], "CORN")]/table[@class="homepage_quoteboard"]')

for row in table.find_elements_by_tag_name('tr')[1:]:  
    priorsettle = str(row.find_element_by_id('quotesFuturesProductTable1_ZSX4_priorSettle').text)

查找表，按索引获取相应的行（此处最简单的方法）：

打印（

先前结算

列）：

请注意，我们需要跳过两行，而不是一行，因为在实际表内容开始之前有两个

tr

标记

table = driver.find_element_by_id('quotesFuturesProductTable1')
for row in table.find_elements_by_tag_name('tr')[2:]:
    print row.find_elements_by_tag_name('td')[4].text
