i am trying to scrape the following page:
https://www.dukascopy.com/swiss/english/marketwatch/sentiment/
more exactly, the numbers in the chart. for example, the number 74,19 % in the green bar next to the aud/usd text. i have inspected the elements and found out that the tag for this number is span. but the following code does not return this or any other number in the chart:
import requests
from bs4 import BeautifulSoup
r=requests.get('https://www.dukascopy.com/swiss/english/marketwatch/sentiment/')
soup = BeautifulSoup(r.content, "html.parser")
data = soup('span')
print(data)
So if you incorporate selenium with beautiful soup, you will get all the abilities of selenium to scrape iframes.
try this:
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.keys import Keys
browser = webdriver.Firefox()
browser.get(bond_iframe)
bond_source = browser.page_source
browser.quit()
soup = BeautifulSoup(bond_source,"html.parser")
for div in soup.findAll('div',attrs={'class':'qs-note-panel'}):
print div
The for loop would be which div tag you are searching for

I wrote this code to fetch the href link of images in webpage. However i found this way to do this, But Unable to find link in loop. I want that when new tab open href link of that tabs get print in shell. And the urls link are multiple.

#driver = webdriver.Chrome(executable_path=r"C:\Users\umesh.kumar\Downloads\Codes\chromedriver.exe")
username = "ABCD.kumar"
password = "X0XX"
driver = webdriver.Chrome()
driver.get("http://propadmin.99acres.com/propadmin/index.htm")
urls = ["https://propadmin.99acres.com/do/seller/ProcessSellerForms/getDeletedPhotos?prop_id=A18056415", "https://propadmin.xxxxxxx.com/do/seller/ProcessSellerForms/getDeletedPhotos?prop_id=A56063622"]
driver.maximize_window()
driver.find_element(By.ID, "username").send_keys(username)
driver.find_element(By.ID, "password").send_keys(password)
driver.find_element_by_name("login").click()
for posts in range(len(urls)):
print(posts)
driver.get(urls[posts])
if(posts!=len(urls)-1):
driver.execute_script("window.open('');")
chwd = driver.window_handles
driver.switch_to.window(chwd[-1])
elems = driver.find_elements_by_tag_name('a')
for elem in elems:
href = elem.get_attribute('href')
if href is not None:
print(href)
I'm trying to use Python (Selenium, BeautifulSoup, and XPath) to scrape a span with an itemprop equal to "description", but every time I run the code, the "try" fails and it prints out the "except" error.
I do see the element in the code when I inspect elements on the page.
Line that isn't getting the desired response:
quick_overview = soup.find_element_by_xpath("//span[contains(#itemprop, 'description')]")
Personally, I think you should just keep working with selenium
quick_overview = driver.find_element_by_xpath("//span[contains(#itemprop, 'description')]")
for the element and add .text to end to get the text content.
To actually use soup to parse this out you would likely need a wait condition from selenium first so no real point.
However, should you decide to integrate bs4 then you need to change your function to work with the actual html from driver.page_source and parse that, then switch to select_one to grab your item. Then ensure you are returning from the function and assigning to new soup object.

I am trying to write a Python program that uses Selenium to click a button to go to the next page if the button is clickable. This is because I am web scraping from varying amounts of pages.
I have tried to use a while loop that checks the href attribute, but the code doesn't click the button, nor does it return an error. If I simply write button.click(), but without a while loop or conditional check for the href attribute, then the program clicks the button correctly.
My code also has a while loop condition of "variable is not None". Is this a valid usage of "is not"? My logic is for the program to click the button to go to the next page if there is an href available from the to click.
Code:
import requests
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
import time
import numpy as np
import pandas as pd
PATH = "C:\Program Files (x86)\chromedriver.exe"
wd = webdriver.Chrome(PATH)
wd.get("https://profiles.ucr.edu/app/home/search;name=;org=Physics%20and%20Astronomy;title=;phone=;affiliation=Faculty")
time.sleep(1)
button = wd.find_element_by_xpath("""//a[#aria-label='Next page']""")
#<a tabindex="0" aria-label="Next page" class="ng-star-inserted" style=""> Next <span class="show-for-sr">page</span></a>
href_data = button.get_attribute('href')
while (href_data is not None):
time.sleep(0.5)
button.click()
href_data = button.get_attribute('href')
Would anyone here be willing to assist me with this? I understand that Selenium requires the user to download a webdriver, so I apologize for any difficulties with testing my code.
Thank you, ExactPlace441
To loop until all pages were clicked.
wd.get('https://profiles.ucr.edu/app/home/search;name=;org=Physics%20and%20Astronomy;title=;phone=;affiliation=Faculty')
wait=WebDriverWait(wd, 10)
while True:
try:
wait.until(EC.element_to_be_clickable((By.XPATH, "//a[#aria-label='Next page']"))).click()
time.sleep(5)
except:
break

I faced the same problem then I used gecko driver(selenium Firefox) instead of Chrome. My code was working perfectly in selenium Firefox but same code was not working in selenium Chrome. Without while loop I hadn't any problem to click on button in selenium Chrome browser but it was not working when added while loop. After using gecko driver(selenium Firefox) my problem was solved. Here is an example of while loop that you can use. It will clicking on button until the button disappeared or reach the last page.
i = 1
try:
while i < 2:
button_element = driver.find_element_by_xpath("give your button xpath")
button_element.click() #Our loop will continuing until our button xpath disappeared from web page
except:
pass #when the button xpath will disappeared it will ignore the error and jump to the next section of our code.
Here I modified your code:

driver.get(url)
timeout = 20
# This container collect data from first page
containers = WebDriverWait(driver, timeout).until(EC.visibility_of_all_elements_located((By.XPATH,'//div[#class="column ng-star-inserted"]' )))
for container in containers:
name = container.find_element_by_css_selector('.header-details h5') #we are srcaping name from each page
print(name.text)
i = 1
try:
while i < 2: #Now it will look for “next page button” in every page and continuing click on “next page button” until it will reach the last page.
next_page_button = driver.find_element_by_xpath("//li[#class='pagination-next ng-star-inserted']")
next_page_button.click()
#our this container2 start collect data from second page to last page
containers = WebDriverWait(driver, timeout).until(EC.visibility_of_all_elements_located((By.XPATH,'//div[#class="column ng-star-inserted"]' )))
for container in containers:
name = container.find_element_by_css_selector('.header-details h5') #we are srcaping name from each page
print(name.text)
time.sleep(3)
except:
pass #if any page don't have “next page button” then our code will be end without any error.
I wrote the python code for web-scraping Sydney morning herald newspaper. This code first clicks all the show more button and then scrape all the articles. Selenium part is working correctly. But I think there is some problem in the scraping part, as after scraping the desired fields (date, title, and content)for few articles (5-6) it is only giving date and title, no content.
import time

import requests
from bs4 import BeautifulSoup
from bs4.element import Tag

browser.get('https://www.smh.com.au/search?text=cybersecurity')
while True:
try:
time.sleep(2)
show_more = wait.until(EC.element_to_be_clickable((By.CLASS_NAME, '_3we9i')))
show_more.click()
except Exception as e:
print(e)
break
soup = BeautifulSoup(browser.page_source,'lxml')
anchors = soup.find_all('a', {'tabindex': '-1'})
for anchor in anchors:
browser.get(base + anchor['href'])
sub_soup = BeautifulSoup(browser.page_source, 'html.parser')
dateTag = sub_soup.find('time', {'class': '_2_zR-'})
titleTag = sub_soup.find('h1', {'itemprop': 'headline'})
contentTag = sub_soup.find_all('div', {'class': '_1665V undefined'})
date = None
title = None
content = None
if isinstance(dateTag, Tag):
date = dateTag.get_text().strip()
if isinstance(titleTag, Tag):
title = titleTag.get_text().strip()
if isinstance(contentTag, list):
content = []
for c in contentTag:
content.append(c.get_text().strip())
content = ' '.join(content)
print(f'{date}\n {title}\n {content}\n')
time.sleep(3)
browser.close()
Why did this code stop giving content part after a few articles? I don't understand it.
Thank you.
It's because You've reached your monthly free access limit
It's the message displayed on the webpage after a few page displayed.
I get an when i try to mix mechanize and BeautifulSoup in the following code:
from BeautifulSoup import BeautifulSoup
import urllib2
import re
import mechanize
br=mechanize.Browser()
br.set_handle_robots(True)
br.open('http://tel.search.ch/')
br.select_form(nr=0)
br.form["was"] = "siemens"
br.submit()
content = br.response
soup = BeautifulSoup(content)
for a in soup.findAll('a',href=True):
if re.findall('title', a['href']):
print "URL:", a['href']
br.close()
The code from the beginning till br.submit() works fine with mechanize and the for loop with BeautifulSoup too. But I don't know how to pass the results from br.submit() into BeautifulSoup. The 2 lines:
content = br.response
soup = BeautifulSoup(content)
are apparently wrong. I get an error for soup = BeautifulSoup(content):
TypeError: expected string or buffer
Can anyone help?
Try changing
content = br.response
to
content = br.response().read()
In this way content now has html that can be passed to BeautifulSoup.
