Webscraping customer review - Invalid selector error using XPath - selenium

Question

I am trying to extract userid, rating and review from the following site using selenium and it is showing "Invalid selector error". I think, the Xpath I have tried to define to get the review text is the reason for error. But I am unable to resolve the issue. The site link is as below:
teslamotor review
The code that I have used is following:
#Class for Review webscraping from consumeraffairs.com site
class CarForumCrawler():
def __init__(self, start_link):
self.link_to_explore = start_link
self.comments = pd.DataFrame(columns = ['rating','user_id','comments'])
self.driver = webdriver.Chrome(executable_path=r'C:/Users/mumid/Downloads/chromedriver/chromedriver.exe')
self.driver.get(self.link_to_explore)
self.driver.implicitly_wait(5)
self.extract_data()
self.save_data_to_file()
def extract_data(self):
ids = self.driver.find_elements_by_xpath("//*[contains(#id,'review-')]")
comment_ids = []
for i in ids:
comment_ids.append(i.get_attribute('id'))
for x in comment_ids:
#Extract dates from for each user on a page
user_rating = self.driver.find_elements_by_xpath('//*[#id="' + x +'"]/div[1]/div/img')[0]
rating = user_rating.get_attribute('data-rating')
#Extract user ids from each user on a page
userid_element = self.driver.find_elements_by_xpath('//*[#id="' + x +'"]/div[2]/div[2]/strong')[0]
userid = userid_element.get_attribute('itemprop')
#Extract Message for each user on a page
user_message = self.driver.find_elements_by_xpath('//*[#id="' + x +'"]]/div[3]/p[2]/text()')[0]
comment = user_message.text
#Adding date, userid and comment for each user in a dataframe
self.comments.loc[len(self.comments)] = [rating,userid,comment]
def save_data_to_file(self):
#we save the dataframe content to a CSV file
self.comments.to_csv ('Tesla_rating-6.csv', index = None, header=True)
def close_spider(self):
#end the session
self.driver.quit()
try:
url = 'https://www.consumeraffairs.com/automotive/tesla_motors.html'
mycrawler = CarForumCrawler(url)
mycrawler.close_spider()
except:
raise
The error that I am getting is as following:
Also, The xpath that I tried to trace is from following HTML

Answer 1

You are seeing the classic error of...
as find_elements_by_xpath('//*[#id="' + x +'"]]/div[3]/p[2]/text()')[0] would select the attributes, instead you need to pass an xpath expression that selects elements.
You need to change as:
user_message = self.driver.find_elements_by_xpath('//*[#id="' + x +'"]]/div[3]/p[2]')[0]
