用Selenium刮不同的表

Question

目前我正在尝试从以下网站中删除所有价格表：http://aeroportos.weebly.com/fuel-prices.html#.W7SatGj7Sbj

但是，我在尝试在xpath中找到表时遇到了一些问题。另外，我不确定是否可以在一个脚本中删除所有表，或者我必须手动检查它们？

def get_prices():
    url = "http://aeroportos.weebly.com/fuel-prices.html#.W7SM3mj7Sbj"
    driver = webdriver.Firefox()
    driver.implicitly_wait(30)
    driver.get(url)
    rows = driver.find_element_by_xpath('//*[@id="wsite-content"]/div/table/tbody').find_elements_by_tag_name('tr')
    prices = []
    for row in rows:
        cells = row.find_elements_by_tag_name('td')
        country = cells[0].text
        code = cells[1].text
        name = cells[2].text
        price = cells[3].text
        prices.append(region, country, code, name, price)
    print(prices)

Answer 1

答案在于编写正确的xpath，它会在页面中的所有表中获取包含数据（没有标题）的所有行。

以下代码应该运行良好：

def get_prices():
    url = "http://aeroportos.weebly.com/fuel-prices.html#.W7SM3mj7Sbj"
    driver = webdriver.Firefox()
    driver.implicitly_wait(30)
    driver.get(url)
    rows = driver.find_element_by_xpath('//*[contains(text(), "Airport")]/ancestor::tr/following-sibling::tr')
    prices = []
    for row in rows:
        cells = row.find_elements_by_tag_name('td')
        region = cells[0].text
        country = cells[1].text
        code = cells[2].text
        name = cells[3].text
        price = cells[4].text
        prices.append(region, country, code, name, price)
    print(prices)

注意：我没有执行代码但它应该运行良好。谢谢。
