通过Selenium选择子css元素无效

Question

在获取元素以单击加号时，代码失败。下面是代码。

    from selenium import webdriver

    driver = webdriver.Chrome()
    driver.get("http://localhost:2012")
    #colIdentList = driver.find_element_by_class_name('colIdent')
    for result in driver.find_elements_by_class_name('colIdent'):
        result.click()
        #wait = WebDriverWait(driver, 5)
        for plus in driver.find_elements_by_class_name('collapser'):
            plus[0].click()
            for methodDiv in driver.find_elements_by_class_name('willnotrender'):
                value = methodDiv[0].text

    driver.close()

“collapser”是驻留在多个div和td下的div的类。我正在粘贴该组件的XPATH作为引用。但是XPATH并不总是相同的，而是不同的。我为元素找到了两个XPath。

XPATH:1/html/body/div[3]/div/ul/li2/div2/div[3]/div2/html/body/div[3]/div/ul/li2/div/div[3]/div

经过一些搜索和朋友Mahesh Kosuri的一点帮助，我终于完成了代码。我错过了网页有多个框架的事实。因此，selenium无法找到我正在搜索的元素。

下面是为我完成任务的代码。

  
    from selenium import webdriver
    from selenium.webdriver.common.keys import Keys
    from selenium.webdriver.common.by import By
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.support import expected_conditions as EC
    import pandas as pd

    timetook,methodname,dbcalls=[],[],[]
    runnum,sheetname,counter=3,7,0
    driver = webdriver.Chrome()
    driver.get("http://localhost:2012/")

    result in driver.find_elements_by_class_name('colIdent'):
        try:
            result.click()
            counter+=1
            if counter>8:
                driver.execute_script("document.querySelector('body > div.trace-list-area').scrollBy(0,75)")
        except:
            driver.execute_script("document.querySelector('body > div.trace-list-area').scrollBy(0,100)")
            result.click()
        driver.switch_to_frame(driver.find_element_by_id('trace-frame'))
        wait = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR,'body > div.scroll-area > div > ul > li:nth-child(2) > div > div.flex-horizontal > div > button')))
        timetook.append(driver.find_elements_by_css_selector('body > div.heading-trace-panel > div.tracebar-details > div > table > tbody > tr > td:nth-child(2) > div.tracebar-value')[0].text)
        driver.find_elements_by_css_selector('body > div.scroll-area > div > ul > li:nth-child(2) > div > div.flex-horizontal > div > button')[0].click()
        methodname.append(driver.find_elements_by_css_selector('#ui_0_stacks > li.logblock.backdrop-timing.logblock-message > div > div.flex-horizontal > div.prettyprint-container')[0].text)
        try:
            dbcalls.append(driver.find_elements_by_css_selector('body > div.heading-trace-panel > div.tracebar-details > div > table > tbody > tr > td.stackNumbers > a > span')[0].get_attribute('data-badge'))
        except:
            dbcalls.append(0)
    driver.switch_to_default_content()

    df=pd.DataFrame()
    df["TimeTook"] = timetook
    df["methodName"]=methodname
    df["DBCalls"]=dbcalls


    df.to_excel("Timing Report "+str(runnum)+"_"+str(sheetname)+".xlsx")
    driver.close()
