我正试图抓住这个网站:
https://www.novanthealth.org/home/patients--visitors/locations/clinics.aspx?behavioral-health=yes
我想获取诊所名称和地址,这是我正在使用的python代码
from selenium import webdriver
import pd
import time
#driver = webdriver.Chrome()
specialty = ["behavioral-health","dermatology","colon","ear-nose-and- throat","endocrine","express","family-practice","foot-and-ankle",
"gastroenterology","heart-%26-vascular","hepatobiliary-and-pancreas","infectious-disease","inpatient","internal-medicine",
"neurology","nutrition","ob%2Fgyn","occupational-medicine","oncology","orthopedics","osteoporosis","pain-management",
"pediatrics","plastic-surgery","pulmonary","rehabilitation","rheumatology","sleep","spine","sports-medicine","surgical","urgent-care",
"urology","weight-loss","wound-care","pharmacy"]
name = []
address = []
for q in specialty:
driver = webdriver.Chrome()
driver.get("https://www.novanthealth.org/home/patients-- visitors/locations/clinics.aspx?"+q+"=yes")
x = driver.find_element_by_class_name("loc-link-right")
num_page = str(x.text).split(" ")
x.click()
for i in num_page:
btn = driver.find_element_by_xpath('//*[@id="searchResults"]/div[2]/div[2]/button['+i+']')
btn.click()
time.sleep(8) #instaed of this use waituntil #
temp = driver.find_element_by_class_name("gray-background").text
temp0 = temp.replace("Get directions Website View providers\n","")
x_temp = temp0.split("\n\n\n")
for j in range(0,len(x_temp)-1):
temp1 = x_temp[j].split("Phone:")
name.append(temp1[0].split("\n")[1])
temp3 = temp1[1].split("Office hours:")
temp4 = temp3[0].split("\n")
temp5 = temp4[1:len(temp4)]
address.append(" ".join(temp5))
driver.close()
这段代码工作正常如果我一次只将它用于一个专业,但是当我按照上面的循环传递专业时,代码在第二次迭代中失败并出现错误:
Traceback (most recent call last):
File "<stdin>", line 10, in <module>

我没有太多使用python的经验,任何帮助将不胜感激

错误消息告诉你它为什么不起作用。
ElementNotVisibleException: Message: element not visible
如果您不向下滚动以查看该元素,则该元素不可见。
您必须根据浏览器的大小向下滚动列表
或
只需从源页面中提取数据,这样更容易。

通常我会在Selenium Basic中做一个excel插件。您可以在Python中使用相同的逻辑。这是在VBA中尝试的,对我来说很好。
