在每個匹配特定類名的元素之后獲取下一個元素

設定

我有以下html表，

<table>
    <tbody>
        <tr class="order-activ_order_delivered">
        <tr class="tracking-url tracking-url-activ_order_delivered">
        <tr class="order-activ_order_delivered">
        <tr class="tracking-url tracking-url-activ_order_delivered">
        <tr class="order-activ_order_delivered">
        <tr class="tracking-url tracking-url-activ_order_delivered">
        <tr class="order-complete">
        <tr class="empty-tracking-url order-complete">
        <tr class="order-activ_order_delivered">
        <tr class="tracking-url tracking-url-activ_order_delivered">
        <tr class="order-activ_order_delivered">
        <tr class="tracking-url tracking-url-activ_order_delivered">
        <tr class="order-complete">
        <tr class="empty-tracking-url order-complete">
    <tbody>
</table>

我只需要類名"order-activ_order_delivered"和行中的資訊"tracking-url tracking-url-activ_order_delivered"。

而且，任何"order-activ_order_delivered"一行的資訊都與后面的"tracking-url tracking-url-activ_order_delivered"行相關。

到目前為止的代碼

以下回圈獲取每個"order-activ_order_delivered",

order_table = el_css(browser,'#my-orders-table > tbody')

for order in order_table.find_elements(By.CSS_SELECTOR,
                           "tr[class^='order-activ_order_delivered']"):
    #code to get data from row

問題

要獲取"tracking-url tracking-url-activ_order_delivered"我嘗試的后續行的資訊，

for order in order_table.find_elements(By.CSS_SELECTOR,
                           "tr[class^='order-activ_order_delivered']"):
    
    order_table.find_elements(By.CSS_SELECTOR,
                           "tr[class^='order-activ_order_delivered']/following-sibling::tr")

但這給出了一個 InvalidSelectorException: invalid selector: An invalid or illegal selector was specified (Session info: chrome=100.0.4896.127)

要么是因為您不能following-sibling在 a 上使用，要么是CSS_SELECTOR因為其他原因。

如何從后續"tracking-url tracking-url-activ_order_delivered"行中獲取？

uj5u.com熱心網友回復：

following-sibling不是CSS_Selector語法它是xpath語法。

您的代碼應該像識別特定元素然后xpath用于檢查following-sibling

 for order in order_table.find_elements(By.CSS_SELECTOR,
                           "tr[class^='order-activ_order_delivered']"):

      nextelement=order.find_element(By.XPATH, "./following-sibling::tr[@class='tracking-url tracking-url-activ_order_delivered']")

或者

for order in order_table.find_elements(By.CSS_SELECTOR,
                               "tr[class^='order-activ_order_delivered']"):
    
          nextelement=order.find_element(By.XPATH, "./following-sibling::tr[1]")

如果想css selector使用可以使用它，它將回傳所有跟蹤 URL。

tr[class^='order-activ_order_delivered'] tr.tracking-url.tracking-url-activ_order_delivered

代碼：

for order in order_table.find_elements(By.CSS_SELECTOR,
                           "tr[class^='order-activ_order_delivered'] tr.tracking-url.tracking-url-activ_order_delivered"):
    nextelement=order
