Webscraping a table into an Excel-file. Its a "Dynamic" table per 10 rows.
All the data is placed into Excel correctly, But having issues with the HREF-data.
The issue i am facing is that some rows dont have a HREF. I am using the following Xpath:
map = driver.find_elements(By.XPATH,'//*[#id="table_1"]/tbody//td[12]/a')
To get the HREF:
.get_attribute("href")[30:].split(",%20")[0]
.get_attribute("href")[30:].split(",%20")[1]
Via above Xpath is can find every HREF, but in case of NO HREF in the row, the following HREF-data is placed into the row where NO HREF-data should be.
Tried the below (without the "/a") but it returns nothing.
map_test = driver.find_elements(By.XPATH, '//*[#id="table_1"]/tbody//td[12]')
When below code is used, it returns the text content which is not what I need, but keeps the data where is should be.
.get_attribute("textContent")
Any idea how i can find the HREFs and keep the data in the rows where it should be?

Basic concept I know:
find_element = find single elements. We can use .text or get.attribute('href') to make the element can be readable. Since find_elements is a list, we can't use .textor get.attribute('href') otherwise it shows no attribute.
To scrape information to be readable from find_elements, we can use for loop function:
vegetables_search = driver.find_elements(By.CLASS_NAME, "product-brief-wrapper")
for i in vegetables_search:
print(i.text)
Here is my problem, when I use find_element, it shows the same result. I searched the problem on the internet and the answer said that it's because using find_element would just show a single result only. Here is my code which hopes to grab different urls.
links.append(driver.find_element(By.XPATH, ".//a[#rel='noopener']").get_attribute('href'))
But I don't know how to combine the results into pandas. If I print these codes, links variable prints the same url on the csv file...
vegetables_search = driver.find_elements(By.CLASS_NAME, "product-brief-wrapper")
Product_name =[]
links = []
for search in vegetables_search:
Product_name.append(search.find_element(By.TAG_NAME, "h4").text)
links.append(driver.find_element(By.XPATH, ".//a[#rel='noopener']").get_attribute('href'))
#use panda modules to export the information
df = pd.DataFrame({'Product': Product_name,'Link': links})
df.to_csv('name.csv', index=False)
print(df)
Certainly, if I use loop function particularly, it shows different links.(That's mean my Xpath is correct(!?))
product_link = (driver.find_elements(By.XPATH, "//a[#rel='noopener']"))
for i in product_link:
print(i.get_attribute('href'))
My questions:
Besides using for loop function, how to make find_elements becomes readable? Just like find_element(By.attribute, 'content').text
How to go further step for my code? I cannot print out different urls.
Thanks so much. ORZ
This is the html code which's inspected from the website:
This line:
links.append(driver.find_element(By.XPATH, ".//a[#rel='noopener']").get_attribute('href'))
should be changed to be
links.append(search.find_element(By.XPATH, ".//a[#rel='noopener']").get_attribute('href'))
driver.find_element(By.XPATH, ".//a[#rel='noopener']").get_attribute('href') will always search for the first element on the DOM matching .//a[#rel='noopener'] XPath locator while you want to find the match inside another element.
To do so you need to change WebDriver driver object with WebElement search object you want to search inside, as shown above.
I am trying to webscrape of 'https://uidb-pbs.tubitak.gov.tr/#tabs-3' website with selenium but I can't get text of neither the table or items of table from web-site. I'm trying to do it like this:
PATH = "C:\Program Files (x86)\chromedriver.exe"
tubitak_ua_driver = webdriver.Chrome(PATH)
tubitak_ua_driver.get("https://uidb-pbs.tubitak.gov.tr/#tabs-3")
project_table = tubitak_ua_driver.find_element_by_xpath('//*[#id="programCagriListTable"]/tbody')
print(project_table.text)
This code doesn't give any error but doesnt give the text either and when I try to get the inner html of the driver I get innerHTML of first tab from website. What is the problem?
Q : Why did your code not work?
The website is poorly designed, there are multiple tables having the same Id in the web page and your code gets the first one which does not have anything inside it. Hence you were getting empty string.
Q : How do we get the desired table.
The desired table is present in the second instance of the query id in your web page. Get the second instance of the returned element and then you can either get the text or load the entire table in a pandas data frame.
table = driver.find_elements_by_xpath('//*[#id="programCagriListTable"]/tbody')
print(table[1].text)
The problem is; there are two elements with this xpath '//*[#id="programCagriListTable"]/tbody' so you need to specify the element that you want. For Example: '(//*[#id="programCagriListTable"]/tbody)[1]'
But if you want the text of an element, you must go to element with text that is
(//table[#id="programCagriListTable"])[2]//descendant::td and to look over with a for
Scrapping links should be a simple feat, usually just grabbing the src value of the a tag.
I recently came across this website (https://sunteccity.com.sg/promotions) where the href value of a tags of each item cannot be found, but the redirection still works. I'm trying to figure out a way to grab the items and their corresponding links. My typical python selenium code looks something as such
all_items = bot.find_elements_by_class_name('thumb-img')
for promo in all_items:
a = promo.find_elements_by_tag_name("a")
print("a[0]: ", a[0].get_attribute("href"))
However, I can't seem to retrieve any href, onclick attributes, and I'm wondering if this is even possible. I noticed that I couldn't do a right-click, open link in new tab as well.
Are there any ways around getting the links of all these items?
Edit: Are there any ways to retrieve all the links of the items on the pages?
i.e.
https://sunteccity.com.sg/promotions/724
https://sunteccity.com.sg/promotions/731
https://sunteccity.com.sg/promotions/751
https://sunteccity.com.sg/promotions/752
https://sunteccity.com.sg/promotions/754
https://sunteccity.com.sg/promotions/280
...
Edit:
Adding an image of one such anchor tag for better clarity:
By reverse-engineering the Javascript that takes you to the promotions pages (seen in https://sunteccity.com.sg/_nuxt/d4b648f.js) that gives you a way to get all the links, which are based on the HappeningID. You can verify by running this in the JS console, which gives you the first promotion:
window.__NUXT__.state.Promotion.promotions[0].HappeningID
Based on that, you can create a Python loop to get all the promotions:
items = driver.execute_script("return window.__NUXT__.state.Promotion;")
for item in items["promotions"]:
base = "https://sunteccity.com.sg/promotions/"
happening_id = str(item["HappeningID"])
print(base + happening_id)
That generated the following output:

You are using a wrong locator. It brings you a lot of irrelevant elements.
Instead of find_elements_by_class_name('thumb-img') please try find_elements_by_css_selector('.collections-page .thumb-img') so your code will be
all_items = bot.find_elements_by_css_selector('.collections-page .thumb-img')
for promo in all_items:
a = promo.find_elements_by_tag_name("a")
print("a[0]: ", a[0].get_attribute("href"))
You can also get the desired links directly by .collections-page .thumb-img a locator so that your code could be:
links = bot.find_elements_by_css_selector('.collections-page .thumb-img a')
for link in links:
print(link.get_attribute("href"))
enter image description hereI want to scrape content from website: https://www.fireant.vn/App#/company-data/ACB.
As far as i know, the content of tablea i want to scrape dynamically rendering data from Angularjs. They use ng-repeat to pass all value like time, volumn, price into the table.
</tr><!-- end ngRepeat: quote in intradayQuotes | orderBy: '-Date' --><tr ng-repeat="quote in intradayQuotes | orderBy: '-Date'" class="ng-scope">
This code from is as far as i can get as i really don't know what kind of object the table is
driver.get('https://www.fireant.vn/App#/company-data/ACB')
driver.set_window_position(0, 0)
driver.set_window_size(100000, 200000)
driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
soup = BeautifulSoup(driver.page_source, 'lxml')
Any instruction on the matter would be much helpful.
Data from table i want to get
print driver.page_source
You'll want to do some digging around on the site to find the CSS selectors (or xpath if you're more comfortable with xml) and use that to get the elements / text that you're interested in.
Instead of using beautiful soup, for Angular (and other Javascript rendered content) you can just grab the data right from webdriver.
for instance:
# driver.find_element_by_css_selector('<SELECTOR FOR THE ELEMENTS YOU WANT>')
prices = driver.find_elements_by_class_name('.price').text
# Returns an array of text of all elements that have the .price class.
Given the screenshot you posted, it seems that Price and Time have identical HTML element attributes -- however, you can use XPath indexing in this case to retrieve the item you want.
To retrieve price:
prices = driver.find_elements_by_xpath("//tbody/tr[2]/td[2]/b[#class='ng-binding']")
Based on the screenshot, it looks like the 'Price' text is in the 2nd tr element under tbody, and 'Price' cell is the 2nd td element under the tr. While I do not normally recommend this type of syntax, your scenario is a special case where the HTML is all nearly identical.
I am trying to extract the most recent headlines from the following news site:
http://news.sina.com.cn/hotnews/
#save ids of relevant buttons that need to be clicked on the site
buttons_ids = ['Tab21' , 'Tab22', 'Tab32']
#save ids of relevant subsections
con_ids = ['Con11']
#start webdriver, go to site, hover over buttons
driver = webdriver.Chrome()
driver.get("http://news.sina.com.cn/hotnews/")
time.sleep(3)
for button_id in buttons_ids:
button = driver.find_element_by_id(button_id)
ActionChains(driver).move_to_element(button).perform()
Then I iterate through each section that I am interested in and within each section through all the headlines which are rows in an HTML table. However, on every iteration, it returns the first element
for con_id in con_ids:
for news_id in range(2,10):
print(news_id)
headline = driver.find_element_by_xpath("//div[#id='"+con_id+"']/table/tbody/tr["+str(news_id)+"]")
text = headline.find_element_by_xpath("//td[2]/a")
print(text.get_attribute("innerText"))
print(text.get_attribute("href"))
com_no = comment.find_element_by_xpath("//td[3]/a")
print(com_no.get_attribute("innerText"))
I also tried the following approach by essentially saving the table as a list and then iterating through the rows:
for con_id in con_ids:
table = driver.find_elements_by_xpath("//div[#id='"+con_id+"']/table/tbody/tr")
for headline in table:
text = headline.find_element_by_xpath("//td[2]/a")
print(text.get_attribute("innerText"))
print(text.get_attribute("href"))
com_no = comment.find_element_by_xpath("//td[3]/a")
print(com_no.get_attribute("innerText"))
In the second case I get exactly the number of headlines in the section, so it apparently correctly picks up the number of rows. However, it is still only returning the first row on all iterations. Where am I going wrong? I know a similar question has been asked here: Selenium Python iterate over a table of rows it is stopping at the first row but I am still unable to figure out where I am going wrong.
In XPath, queries that begin with // will search relative to the document root; so even though you're calling find_element_by_xpath() on the correct container element, you're breaking out of that scope, thereby performing the same global search and yielding the same result every time.
To constrain your query to descendants of the current element, begin your query with .//, e.g.,:
text = headline.find_element_by_xpath(".//td[2]/a")
try this:
for con_id in con_ids:
for news_id in range(2,10):
print(news_id)
print("(//div[#id='"+con_id+"']/table/tbody/tr)["+str(news_id)+"]")
headline = driver.find_element_by_xpath("(//div[#id='"+con_id+"']/table/tbody/tr)["+str(news_id)+"]")
value = headline.find_element_by_xpath(".//td[2]/a")
print(value.get_attribute("innerText").encode('utf-8'))
I am able to get the headlines with above code
I was able to solve it by specifying the entire XPath in one go like this:
headline = driver.find_element_by_xpath("(//*[#id='"+con_id+"']/table/tbody/tr["+str(news_id)+"]/td[2]/a)")
print(headline.get_attribute("innerText"))
print(headline.get_attribute("href"))
rather than splitting it into two parts.
My only explanation for why it only prints the first row repeatedly is that there is some weird Javascript at work that doesn't let you iterate properly when splitting the request.
Or my first version had a syntax error, which I am not aware of.
If anyone has a better explanation, I'd be glad to hear it!
