Question

我正在使用Python和Selenium刮擦一个网站。使用find_by_element来查找我需要的所有值，但遇到了更多挑战。网站html将确切的结构显示为两个不同的值，我不能使用简单的find_element_by_class，因为它们具有相同的类和ID。我不想使用xpath或选择器，因为我正在许多“ flight-row” div中进行迭代，这会使思想更加硬编码。

<div class="flight-row">
    <div class="row row-eq-heights">
        <div class="col-xs-4 col-md-4 no-padding"><span class="airline-name">gol</span><span class="flight-number">AM-477</span></div>
        <div class="col-xs-4 col-md-4">
            <div class="flight-timming"><span class="flight-time">06:15</span><span class="flight-destination">IAH</span></div><span class="flight-data">01/10/19</span></div>
        <div class="col-xs-4 col-md-4 no-padding">
            <div class="duration"><span class="flight-duration">21:25</span><span class="flight-stops" aria-label="Paradas do voo">2 paradas</span></div>
        </div>
        <div class="col-xs-4 col-md-4">
            <div class="flight-timming"><span class="flight-destination">GIG</span><span class="flight-time">05:40</span></div><span class="flight-data">02/10/19</span></div>
    </div>
</div>

我想从两个“ col-xs-4 col-md-4” div的飞行时间，飞行目的地和飞行数据中获取值。

这是我的一些代码：

outbound_flights = driver.find_elements_by_css_selector("div[class^='flight-item ']")

for outbound_flight in outbound_flights:
    airline = outbound_flight.find_element_by_css_selector("span[class='airline-name']")

谢谢！

Answer 1

您可以按索引获取值。

(//*[@class='flight-time'])[1]和(//*[@class='flight-time'])[2]

Answer 2

尝试使用以下CSS选择器获取flight-time，flight-destination和flight-data

outbound_flights = driver.find_elements_by_css_selector("div.col-xs-4.col-md-4:not(.no-padding)")

for outbound_flight in outbound_flights:
    flight_time = outbound_flight.find_element_by_css_selector("div.flight-timming span.flight-time").text
    print(flight_time)
    flight_destination = outbound_flight.find_element_by_css_selector("div.flight-timming span.flight-destination").text
    print(flight_destination)
    flight_data = outbound_flight.find_element_by_css_selector("span.flight-data").text
    print(flight_data)

控制台上的输出：

06:15
IAH
01/10/19
05:40
GIG
02/10/19

已编辑答案：

outbound_flights = driver.find_elements_by_css_selector("div.col-xs-4.col-md-4:not(.no-padding)")
flighttime=[]
for outbound_flight in outbound_flights:
    flight_time = outbound_flight.find_element_by_css_selector("div.flight-timming span.flight-time").text
    print(flight_time)
    flighttime.append(flight_time)
    flight_destination = outbound_flight.find_element_by_css_selector("div.flight-timming span.flight-destination").text
    print(flight_destination)
    flight_data = outbound_flight.find_element_by_css_selector("span.flight-data").text
    print(flight_data)

departure_time=flighttime[0]
arrival_time=flighttime[1]

print("Departure time :" + departure_time)
print("Arrival time :" + arrival_time)

使用Selenium在同一类的两个不同的div中查找不同的元素
