我正在阅读一个 Docx 文件 [此处是链接]，从中解析一些文本，然后使用 python selenium 绑定和 chrome-driver 尝试单击源 (driver.page_source) 中的隐藏选项值。我知道它不可供选择。这是我到目前为止的代码：
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::', '(.+?)'")

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$ddlMerk"]/option[@value="130"]').click() #except: driver.quit() time.sleep(5) driver.quit()
因此，使用请求模块我向链接发出 POST 请求并设法获得具有所需选项数据的响应，请参见此处：
<select name="ctl00$cp$ucSearch_Manual$ddlMerk" onchange="updateInputForServerNoPB();InvalidateVehicleSearchResult();setTimeout('__doPostBack(\'ctl00$cp$ucSearch_Manual$ddlMerk\',\'\')', 0)" id="ctl00_cp_ucSearch_Manual_ddlMerk" class="NormalDropdownlist" style="width:174px;"> <option selected="selected" value="-1">- Kies merk -</option> <option value="95">Alfa Romeo</option> <option value="154">Aston Martin</option> <option value="96">Audi</option> <option value="97">Bentley</option> <option value="98">BMW</option> <option value="352">Bugatti</option> <option value="100">Cadillac</option> <option value="342">Chevrolet</option> <option value="101">Chevrolet USA</option> <option value="102">Chrysler</option> <option value="103">Citroen</option> <option value="337">Corvette</option> <option value="104">Dacia</option> <option value="105">Daihatsu</option> <option value="166">Daimler</option> <option value="162">Dodge</option> <option value="106">Donkervoort</option> <option value="107">Ferrari</option> <option value="108">Fiat</option> <option value="94">Ford</option> <option value="111">Honda</option> <option value="340">Hummer</option> <option value="112">Hyundai</option> <option value="365">Infiniti</option> <option value="113">Jaguar</option> <option value="114">Jeep</option> <option value="150">Kia</option> <option value="115">Lada</option> <option value="116">Lamborghini</option> <option value="117">Lancia</option> <option value="168">Land Rover</option> <option value="432">Landwind</option> <option value="118">Lexus</option> <option value="119">Lotus</option> <option value="120">Maserati</option> <option value="330">Maybach</option> <option value="121">Mazda</option> <option value="122">Mercedes-Benz</option> <option value="304">Mini</option> <option value="124">Mitsubishi</option> <option value="126">Morgan</option> <option value="127">Nissan</option> <option value="128">Opel</option> <option value="130">Peugeot</option> <option value="132">Porsche</option> <option value="134">Renault</option> <option value="135">Rolls-Royce</option> <option value="138">Saab</option> <option value="139">Seat</option> <option value="140">Skoda</option> <option value="226">smart</option> <option value="343">Spyker</option> <option value="210">SsangYong</option> <option value="141">Subaru</option> <option value="142">Suzuki</option> <option value="417">Think</option> <option value="144">Toyota</option> <option value="147">Volkswagen</option> <option value="145">Volvo</option> </select>
，我想知道是否有办法将上述字符串文本添加到driver.page_source，以便我可以使用驱动程序属性遍历选项值？
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"
此代码会有所帮助。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，可以使用以下方法：
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：
