Python 3.x 使用xpath和contains选项单击按钮

我有一个页面，我需要单击满足条件的特定按钮，我已经相应地编写了代码，但是当单击按钮事件不满足contains条件时会出现问题，因为我得到了InvaliseSelect或Exception，我相信我在编写xpath时犯了错误

在我正在抓取的页面中，有多行，每行有四列，因此对于每行，我将列中的每个元素分别附加到列表中，并使用enumerate检查按钮文本的条件，以获取列表的索引，其中按钮的文本是具有这些文本我想检查所有的值，比如第一个元素，第二个元素，第三个元素，第四个元素，然后单击所有这些条件都存在的行的td中的元素

for row in rows:
    try:
        SizeOfContainer = row.find_element_by_xpath('//*[@id="text-size"]/span').text.replace('Double \n Doors', "")
        SizeOfContainer1 = SizeOfContainer.replace('HC', "")
        SizeOfContainer2 = SizeOfContainer1.replace('Double Doors', "")
        SizeOfContainer3 = SizeOfContainer2.replace('\n', "")
        SizeOfContainer4 = SizeOfContainer3.replace('DoubleDoors', "")
        print(SizeOfContainer4)
        SizeOfContainers.append(SizeOfContainer4)
        Ranking = row.find_element_by_xpath('td[2]/b').text
        Ranking1 = Ranking.replace('\n',"")
        print(Ranking1)
        Rankingofcont.append(Ranking1)
        Price = row.find_element_by_xpath('td[3]/h4').text
        pricelist.append(Price)
        print(Price)
        DeliveryAvailable = row.find_element_by_xpath('td[4]').text
        print(DeliveryAvailable)
        deliveryav.append(DeliveryAvailable)
        CityName = DeliveryAvailable.replace("Yes, to","")
        try:
            delsta = row.find_element_by_xpath('td[5]/a/b').text
        except NoSuchElementException:
            delsta = row.find_element_by_xpath('td[5]/form/button/b').text
        print(delsta)
        delstatus.append(delsta)
    except NoSuchElementException:
        pass
    listnumbcond = [i for i, x in enumerate(delstatus) if x == "View Delivery Cost »"]
    print(listnumbcond)
    pricenew=[]
    SizeOfContainersnew = []
    Rankingofcontnew = []
    deliveryavnew = []
    for i in listnumbcond:
        pricenew.append(pricelist[i])
    for i in listnumbcond:
        SizeOfContainersnew.append(SizeOfContainers[i])
    for i in listnumbcond:
        Rankingofcontnew.append(Rankingofcont[i])
    for i in listnumbcond:
        deliveryavnew.append(deliveryav[i])
    print(pricenew)

    for j in pricenew:
        ss = pricenew.index(j)
        print(ss)
        aj = SizeOfContainersnew[ss]
        print(aj)
        ag = Rankingofcontnew[ss]
        print(ag)
        adf = deliveryavnew[ss]
        aj1 = str(aj)
        g = str(j)
        ddjel = "//*[contains(text()," + '"' +aj1 + '"' + ")]"+"//*[contains(text()," + '"' +ag + '"' + ")]"+"//*[contains(text()," + '"' +g + '"'+ ")]"+"'//*[contains(text()," + '"' +adf + '"' + ")]/../[@class="+"'button radius small dropshadowtiny margin4r'"+"]'"
        Delivery_cost = row.find_element_by_xpath(ddjel).click()
        delivery_details()

我希望检查td是否包含第一个文本，然后在下一个td中检查第二个文本的值，然后在第三个td文本中检查第三个td文本，然后在满足所有条件的情况下检查第八个td文本，然后单击第五个td按钮

所有这些要检查的值都是从我存储它的列表中获取的

我已经附加了页面的图像和它的html标签

以下是html代码：

    <div class="inline min-120">
