使用 python selenium chromedriver 从源中选择隐藏的选项值

Question

我正在阅读一个 Docx 文件 [这里是 link] ，从中解析一些文本，然后使用 python selenium bindings & chrome-driver 我试图单击源 (driver.page_source) 中的隐藏选项值。我知道它无法选择。到目前为止，这是我的代码：

import time, re
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from docx import opendocx, getdocumenttext
from requests import Session

def read_return(word_file):
    document = opendocx(word_file)
    paratextlist = getdocumenttext(document)
    newparatextlist = []
    for paratext in paratextlist:
        newparatextlist.append((paratext.encode("utf-8")).strip('\n').strip('\t').strip('\r'))
    newparatextlist = str(newparatextlist).replace("]","").replace("[","")
    with open('sample.txt','wb')as writer:
        writer.write(newparatextlist)
    return newparatextlist

word_file = read_return('Taxatierapport SEK - Auto Centrum Bollenstreek - Peugeot 308 - 5603.docx')

x = lambda x:re.findall(x,word_file,re.DOTALL)[0].strip().replace("'","'").replace('"',''')
Voertuig = x("::OBJECT::', '(.+?)'")

Merk = x("::MERK::', '(.+?)'")
Model = x("::TYPE::', '(.+?)'")
TOELATING = x("::BOUWJAAR 1STE TOELATING::', '(.+?)'")
d1 = TOELATING.split("-")[0]
d2 = TOELATING.split("-")[1]
d3 = TOELATING.split("-")[2]
TRANSMISSIE = x("::TRANSMISSIE::', '(.+?)'")
BRANDSTOF = x("::BRANDSTOF::', '(.+?)'")

print "%r\n%r\n%r\n%r\n%r\n%r\n%r\n%r\n" %(Voertuig, Merk, Model, d1, d2, d3, TRANSMISSIE, BRANDSTOF)

if Voertuig == "Personenauto":
    value = 1
elif Voertuig == "Personenbussen":
    value = 7
elif Voertuig == "Bedrijfsauto's tot 3.5 ton":
    value = 3
elif Voertuig == "Bedrijfsauto's 4x4":
    value = 2
elif Voertuig == "Motoren":
    value= 5

xr = 0; yr = 0; zr = 1972
while xr < 32:
    if int(d1) == xr:
        dvalue1 = xr
    else:
        pass
    xr+=1

while yr < 13:
    if int(d2) == yr:
        dvalue2 = yr
    else:
        pass
    yr+=1

while zr < 2018:
    if int(d3) == zr:
        dvalue3 = zr
    else:
        pass
    zr+=1

driver = webdriver.Chrome('chromedriver.exe')
driver.get('https://autotelexpro.nl/LoginPage.aspx')
driver.find_element(By.XPATH, value ='//*[@id="ctl00_cp_LogOnView_LogOn_txtVestigingsnummer"]').send_keys('3783')
driver.find_element(By.XPATH, value ='//*[@id="ctl00_cp_LogOnView_LogOn_txtGebruikersnaam"]').send_keys('Frank')
driver.find_element(By.XPATH, value ='//*[@id="ctl00_cp_LogOnView_LogOn_Password"]').send_keys('msnauto2016')
driver.find_element(By.XPATH, value ='//*[@id="ctl00_cp_LogOnView_LogOn_btnLogin"]').click()
time.sleep(10)
#try:
driver.find_element(By.XPATH, value ='//select[@name="ctl00$cp$ucSearch_Manual$ddlVoertuigType"]/option[@value="'+str(value)+'"]').click()
driver.find_element(By.XPATH, value ='//select[@name="ctl00$cp$ucSearch_Manual$ddlBouwdag"]/option[@value="'+str(dvalue1)+'"]').click()
driver.find_element(By.XPATH, value ='//select[@name="ctl00$cp$ucSearch_Manual$ddlBouwmaand"]/option[@value="'+str(dvalue2)+'"]').click()
driver.find_element(By.XPATH, value ='//select[@name="ctl00$cp$ucSearch_Manual$ddlBouwjaar"]/option[@value="'+str(dvalue3)+'"]').click()
driver.find_element(By.XPATH, value ='//select[@name="ctl00$cp$ucSearch_Manual$ddlMerk"]/option[@value="130"]').click()
#except:
driver.quit()

time.sleep(5)
driver.quit()

所以使用请求模块我向链接发出 POST 请求并设法获得具有所需选项数据的响应，请参见此处：

<select name="ctl00$cp$ucSearch_Manual$ddlMerk" onchange="updateInputForServerNoPB();InvalidateVehicleSearchResult();setTimeout(&#39;__doPostBack(\&#39;ctl00$cp$ucSearch_Manual$ddlMerk\&#39;,\&#39;\&#39;)&#39;, 0)" id="ctl00_cp_ucSearch_Manual_ddlMerk" class="NormalDropdownlist" style="width:174px;">

    </select>

，我想知道是否可以将上述字符串文本添加到 driver.page_source 中，以便我可以使用 driver 属性迭代选项值？

Answer 1

from selenium import webdriver
from selenium.webdriver.common.by import By
import time
from selenium.webdriver.support.ui import Select


driver = webdriver.Chrome()
driver.maximize_window()
driver.get('https://autotelexpro.nl/LoginPage.aspx')
driver.find_element(By.XPATH, value ='//*[@id="ctl00_cp_LogOnView_LogOn_txtVestigingsnummer"]').send_keys('3783')
driver.find_element(By.XPATH, value ='//*[@id="ctl00_cp_LogOnView_LogOn_txtGebruikersnaam"]').send_keys('Frank')
driver.find_element(By.XPATH, value ='//*[@id="ctl00_cp_LogOnView_LogOn_Password"]').send_keys('msnauto2016')
driver.find_element(By.XPATH, value ='//*[@id="ctl00_cp_LogOnView_LogOn_btnLogin"]').click()
time.sleep(10)


currentselection = driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlVoertuigType']")
select = Select(currentselection)
select.select_by_visible_text("Motoren")
time.sleep(5)

try:
    x=driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlBouwdag']")
    select = Select(x)
    select.select_by_visible_text("1")

    y=driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlBouwmaand']")
    select = Select(y)
    select.select_by_visible_text("1")

    z=driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlBouwjaar']")
    select = Select(z)
    select.select_by_visible_text("2017")
    time.sleep(5)


    car = driver.find_element_by_css_selector("#ctl00_cp_ucSearch_Manual_ddlMerk")
    select = Select(car)
    select.select_by_visible_text("BTC")
except:
    print "Not able to select"

这段代码会有所帮助。 查看更好的方法是显式等待，但对于临时解决方案，我使用了 time.sleep()

更新：如果您想从汽车下拉菜单中获取选项，这是一种可以使用的方法：

def getallcarlist():
    currentselection = driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlVoertuigType']")
    select = Select(currentselection)
    select.select_by_visible_text("Motoren")
    time.sleep(5)

    x = driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlBouwdag']")
    select = Select(x)
    select.select_by_visible_text("1")

    y = driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlBouwmaand']")
    select = Select(y)
    select.select_by_visible_text("1")

    z = driver.find_element_by_xpath(".//*[@id='ctl00_cp_ucSearch_Manual_ddlBouwjaar']")
    select = Select(z)
    select.select_by_visible_text("2017")
    time.sleep(5)

    car = driver.find_element_by_css_selector("#ctl00_cp_ucSearch_Manual_ddlMerk")
    carlist =[]
    for option in car.find_elements_by_tag_name('option'):
        carlist.append((option.text).encode('utf8'))
    return carlist

这是称呼它的方式

listcar= getallcarlist()
for c in listcar:
    print c

输出将是：
