python - 'list' object has no attribute 'get_attribute' while iterating through WebElements

Question

I'm trying to use Python and Selenium to scrape multiple links on a web page. I'm using find_elements_by_xpath and I'm able to locate a list of elements but I'm having trouble changing the list that is returned to the actual href links. I know find_element_by_xpath works, but that only works for one element.

Here is my code:

path_to_chromedriver = 'path to chromedriver location'
browser = webdriver.Chrome(executable_path = path_to_chromedriver)

browser.get("file:///path to html file")

all_trails = []

#finds all elements with the class 'text-truncate trail-name' then 
#retrieve the a element
#this seems to be just giving us the element location but not the 
#actual location

find_href = browser.find_elements_by_xpath('//div[@class="text truncate trail-name"]/a[1]')
all_trails.append(find_href)

print all_trails

This code is returning:

<selenium.webdriver.remote.webelement.WebElement 
(session="dd178d79c66b747696c5d3750ea8cb17", 
element="0.5700549730549636-1663")>, 
<selenium.webdriver.remote.webelement.WebElement 
(session="dd178d79c66b747696c5d3750ea8cb17", 
element="0.5700549730549636-1664")>,

I expect the all_trails array to be a list of links like: www.google.com, www.yahoo.com, www.bing.com.

I've tried looping through the all_trails list and running the get_attribute('href') method on the list but I get the error:

Does anyone have any idea how to convert the selenium WebElement's to href links?

Any help would be greatly appreciated :)

Let us see what's happening in your code :

Without any visibility to the concerned HTML it seems the following line returns two WebElements in to the List find_href which are inturn are appended to the all_trails List :

find_href = browser.find_elements_by_xpath('//div[@class="text truncate trail-name"]/a[1]')

Hence when we print the List all_trails both the WebElements are printed. Hence No Error.

As per the error snap shot you have provided, you are trying to invoke get_attribute("href") method over a List which is Not Supported. Hence you see the error :

'List' Object has no attribute 'get_attribute'

Solution :

To get the href attribute, we have to iterate over the List as follows :

find_href = browser.find_elements_by_xpath('//your_xpath')
for my_href in find_href:
    print(my_href.get_attribute("href"))
