I am trying to do some web scrawling through Selenium. However, when I run the code, it does not show the result.
Here is my code:
import selenium
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from bs4 import BeautifulSoup
import time
import pandas as pd
driver = webdriver.Chrome()
url = 'https://vimeo.com/510879223'
driver.get(url)
#head > meta:nth-child(14)
#/html/head/meta[8]
title = driver.find_element(By.CSS_SELECTOR,"head > meta:nth-child(14)")
print (title.text)
description = driver.find_element(By.XPATH,"//meta[#property='og:description']").text
print (description)
Result:
Process finished with exit code 0
In this case, what should I add or delete? Is it happened because the site that I want to scrape does not support xpath scrape option?
If I do print (title), the result is:
<selenium.webdriver.remote.webelement.WebElement (session="6f182a4afb7c1173f1e74f1cd6a40d87", element="e10f1407-3a09-4f3e-96e4-19071cda7d8e")>
Feel like it has a result but I cannot check the result as text. In this case, what is the best way to fix it? Thank you!
In your case I would recommend finding title by Xpath since the css selector you are trying to use is showing me the description tag. Notice that the text you are looking for is not stored as text on the page but rather in the content attribute. Using the .get_attribute() method should help.
title = driver.find_element(By.XPATH,"//meta[#property='og:title']").get_attribute('content')
print (title)
description = driver.find_element(By.XPATH,"//meta[#property='og:description']").get_attribute('content')
print (description)
Hi sometimes errors may occur in xpath copying. There may be inconsistencies with the command you want to take action.You can try using commands.
find_element_by_css_selector
find_element_by_class_name
My example project may help you.

I am trying to scrape a list of specific movies from IMDB using this tutorial.
The code is working fine expect for the for click to get the URL then saves in content. It is not working. The issue is that nothing change in chrome when running the code I really appreciate if anyone can help.
content = driver.find_element_by_class_name("tF2Cxc").click()
import requests
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import pandas as pd
from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer
import time
movie = 'Wolf Totem'
driver = webdriver.Chrome(executable_path=r"D:\chromedriver.exe")
#Go to Google
driver.get("https://www.google.com/")
#Enter the keyword
driver.find_element_by_name("q").send_keys(movie + " imdb")
time.sleep(1)
#Click the google search button
driver.find_element_by_name("btnK").send_keys(Keys.ENTER)
time.sleep(1)
You are using a wrong locator.
To open the a search result on Google page you should use this:
driver.find_element_by_xpath("//div[#class='yuRUbf']/a").click()
This locator will match all the 10 search results, so the first match is the first search result.
Also, clicking on that element will not give you any content, just open the first link below the title of the first search result.
I am scraping news articles related to Infosys at the end of page but getting error
selenium.common.exceptions.InvalidSelectorException: Message: invalid selector .
Want to scrape all articles related to Infosys.
from bs4 import BeautifulSoup
import re
from selenium import webdriver
import chromedriver_binary
import string
import time
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
driver = webdriver.Chrome("/Users/abhishekgupta/Downloads/chromedriver")
driver.get("https://finance.yahoo.com/quote/INFY/news?p=INFY")
for i in range(20): # adjust integer value for need
# you can change right side number for scroll convenience or destination
driver.execute_script("window.scrollBy(0, 250)")
# you can change time integer to float or remove
time.sleep(1)
print(driver.find_element_by_xpath('//*[#id="latestQuoteNewsStream-0-Stream"]/ul/li[9]/div/div/div[2]/h3/a/text()').text())
You could use less detailed xpath using // instead of /div/div/div[2]
And if you want last item then get all li as list and later use [-1] to get last element on list
from selenium import webdriver
import time
driver = webdriver.Chrome("/Users/abhishekgupta/Downloads/chromedriver")
#driver = webdriver.Firefox()
driver.get("https://finance.yahoo.com/quote/INFY/news?p=INFY")
for i in range(20):
driver.execute_script("window.scrollBy(0, 250)")
time.sleep(1)
all_items = driver.find_elements_by_xpath('//*[#id="latestQuoteNewsStream-0-Stream"]/ul/li')
#for item in all_items:
# print(item.find_element_by_xpath('.//h3/a').text)
# print(item.find_element_by_xpath('.//p').text)
# print('---')
print(all_items[-1].find_element_by_xpath('.//h3/a').text)
print(all_items[-1].find_element_by_xpath('.//p').text)
xPath you provided does not exist in the page.
Download the xPath Finder Chrome Extension to find the correct xPath for articles.
Here is an example xPath of articles list, you need to loop through id:
/html/body/div[1]/div/div/div[1]/div/div[3]/div[1]/div/div[5]/div/div/div/ul/li[ID]/div/div/div[2]/h3/a/u
I think your code is fine just one thing: there are few difference when we retrieve text or links when using xpath in selenium as compare to scrapy or if you are using lxml fromstring library so here is something that should work for you
#use this code for printing instead
print(driver.find_element_by_xpath('//*[#id="latestQuoteNewsStream-0- Stream"]/ul/li[9]/div/div/div[2]/h3/a').text)
Even if you do this it will work the same way since there is only one element with this id so simply use
#This should also work fine
print(driver.find_element_by_xpath('//*[#id="latestQuoteNewsStream-0- Stream"]').text)
I have started selenium using python. I am able to change the message text using find_element_by_id. I want to do the same with find_element_by_xpath which is not successful as the xpath has two instances. want to try this out to learn about xpath.
I want to do web scraping of a page using python in which I need clarity on using Xpath mainly needed for going to next page.
#This code works:
import time
import requests
import requests
from selenium import webdriver
driver = webdriver.Chrome()
url = "http://www.seleniumeasy.com/test/basic-first-form-demo.html"
driver.get(url)
eleUserMessage = driver.find_element_by_id("user-message")
eleUserMessage.clear()
eleUserMessage.send_keys("Testing Python")
time.sleep(2)
driver.close()
#This works fine. I wish to do the same with xpath.
#I inspect the the Input box in chrome, copy the xpath '//*[#id="user-message"]' which seems to refer to the other box as well.
# I wish to use xpath method to write text in this box as follows which does not work.
driver = webdriver.Chrome()
url = "http://www.seleniumeasy.com/test/basic-first-form-demo.html"
driver.get(url)
eleUserMessage = driver.find_elements_by_xpath('//*[#id="user-message"]')
eleUserMessage.clear()
eleUserMessage.send_keys("Test Python")
time.sleep(2)
driver.close()
To elaborate on my comment you would use a list like this:
eleUserMessage_list = driver.find_elements_by_xpath('//*[#id="user-message"]')
my_desired_element = eleUserMessage_list[0] # or maybe [1]
my_desired_element.clear()
my_desired_element.send_keys("Test Python")
time.sleep(2)
The only real difference between find_elements_by_xpath and find_element_by_xpath is the first option returns a list that needs to be indexed. Once it's indexed, it works the same as if you had run the second option!
I am trying to scrape a public facebook group using beautifulsoup, I am using the mobile site for the lack of javascript there. So this script supposed to get the link from the 'more' keyword and get the text from p tag there, but it just gets the text from the current page's p tag. Can someone point me the problem? I am new to python and everything in this code.
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.common.exceptions import NoSuchElementException
from bs4 import BeautifulSoup
import requests
browser = webdriver.Firefox()
browser.get('https://mobile.facebook.com/groups/22012931789?refid=27')
for elem in browser.find_elements_by_link_text('More'):
page = requests.get(elem.get_attribute("href"))
soup=BeautifulSoup(page.content,'html.parser')
print(soup.find_all('p')[0].get_text())
It's always useful to see what your script is actually doing, a quick way of doing this is by printing your results at certain steps along the way.
For example, using your code:
for elem in browser.find_elements_by_link_text('More'):
print("elem's href attribute: {}".format(elem.get_attribute("href")))
You'll notice that the first one's blank. We should test for this before trying to get requests to fetch it:
for elem in browser.find_elements_by_link_text('More'):
if elem.get_attribute("href"):
print("Trying to get {}".format(elem.get_attribute("href")))
page = requests.get(elem.get_attribute("href"))
soup=BeautifulSoup(page.content,'html.parser')
print(soup.find_all('p')[0].get_text())
Note that an empty elem.get_attribute("href") returns an empty unicode string, u'' - but pythons considers an empty string to be false, which is why that if works.
Which works fine on my machine. Hope that helps!
I'm just learning python and decided to play with some website scraping.
I created 1 that works, and a second, almost identical as far as I can tell, that doesn't work, and I can't figure out why.
from lxml import html
import requests
page = requests.get('https://thronesdb.com/set/Core')
tree = html.fromstring(page.content)
cards = [tree.xpath('//a[#class = "card-tip"]/text()'),tree.xpath('//td[#data-th = "Faction"]/text()'),
tree.xpath('//td[#data-th = "Cost"]/text()'),tree.xpath('//td[#data-th = "Type"]/text()'),
tree.xpath('//td[#data-th = "STR"]/text()'),tree.xpath('//td[#data-th = "Traits"]/text()'),
tree.xpath('//td[#data-th = "Set"]/text()'),tree.xpath('//a[#class = "card-tip"]/#data-code')]
print(cards)
That one does what I expect (I know it's not pretty). It grabs certain elements from a table on the site.
This one returns [[]]:
from lxml import html
import requests
page = requests.get('http://www.redflagdeals.com/search/#!/q=baby%20monitor')
tree = html.fromstring(page.content)
offers = [tree.xpath('//a[#class = "offer_title"]/text()')]
print(offers)
What I expect it to do is give me a list that has the text from each offer_title element on the page.
The xpath I'm gunning at I grabbed from Firebug, which is:
/html/body/div[1]/div/div/div/section/div[2]/ul[1]/li[2]/div/h3/a
Here's the actual string from the site:
Angelcare Digital Video And Sound Monitor - $89.99 ($90.00 Off)
I have also read a few other questions, but they didn't answer how this could work the first way, but not the second. Can't post them because of the link restrictions on new accounts.

Any help would be appreciated. I did some reading on the lxml website about xpath, but I may be missing something in the way I'm building a query.
Thanks!
The reason why the first code is working is that required data is initially present in DOM while on second page required data is generated dynamically by JavaScript, so you cannot scrape it because requests doesn't support handling dynamic content.
You can try to use, for example, Selenium + PhantomJS to get required data as below:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait as wait
driver = webdriver.PhantomJS(executable_path='/path/to/phantomJS')
driver.get('http://www.redflagdeals.com/search/#!/q=baby%20monitor')
xpath = '//a[#class = "offer_title"]'
wait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, xpath)))
offers = [link.get_attribute('textContent') for link in driver.find_elements_by_xpath(xpath)]
