Question

我正在尝试访问页面中的每个名称，然后抓取HTML代码。由于有多个页面，我试图使用循环。我想访问的每个“行”都有相同的xpath;唯一改变的是它中的数字。当我尝试运行代码时，我得到No such element: Unable to locate element。是因为str（x）不适合xpath吗？

def check_exists_by_xpath(xpath):
    try: 
       driver.find_element_by_xpath(xpath)
    except NoSuchElementException:
       return False
    return True  

base_url =r"https://threedecks.org/index.php?display_type=crewman_search"

path_driver = r"C:\Program Files 
(x86)\Google\Chrome\Application\chromedriver.exe"

driver = webdriver.Chrome(path_driver)    
driver.get(base_url)

pic_path0="//*[@id=\"nation\"]"
driver.find_element_by_xpath(pic_path0).send_keys('Great Britain')
time.sleep(1)
pic_path1="//*[@id=\"roles\"]"
driver.find_element_by_xpath(pic_path1).send_keys('Sailor')
pic_path2="//*[@id=\"form_row_Search\"]/input"  
driver.find_element_by_xpath(pic_path2).click()

for x in xrange(0,51):
    pic_path3="//*[@id=\"crew_search_results\"]/tbody/tr[" + str(x)
    +"]/td[2]/a"

    driver.find_element_by_xpath(pic_path3).click()
    info=get_attribute("href")
    time.sleep(1)

    scraped = open('C:\Users\emarchesi\Desktop\links.txt',"wt")
    scraped.write(info)
    scraped.close()

用硒刮痧。没有这样的元素：由于循环无法定位元素？
