Question

I am trying to extract data from HTML table. Successfully counted the row but when I'm printing it keeps repeating the row. Can anyone please tell me what is wrong in code? Thanks.

#counting length of row
rows = len(driver.find_elements_by_xpath('/html/body/form/fieldset/table[2]/tbody/tr/td[3]/table/tbody/tr[5]/td[2]/div/table[1]/tbody/tr[2]/td[1]/table[2]/tbody/tr'))
time.sleep(2)
print(rows)

for r in range(rows):
    value=driver.find_element_by_xpath('/html/body/form/fieldset/table[2]/tbody/tr/td[3]/table/tbody/tr[5]/td[2]/div/table[1]/tbody/tr[2]/td[1]/table[2]/tbody/tr["+str(r)+"]')
    print(value.text)


#Output:
18 #no of rows
Start of legal relation2/7/2018 #1st row
Start of legal relation2/7/2018
Start of legal relation2/7/2018
Start of legal relation2/7/2018

Without a URL you have supplied, it's difficult to say why. However, the first tr element would be [1] , so I think your range function should be range(1, rows + 1) . And the way you are going about this seems very indirect since your first query seems to have retrieved all the elements you are looking for. So why not just the following?

elements = driver.find_elements_by_xpath('/html/body/form/fieldset/table[2]/tbody/tr/td[3]/table/tbody/tr[5]/td[2]/div/table[1]/tbody/tr[2]/td[1]/table[2]/tbody/tr')
#time.sleep(2) # what does this accomplish?
print(len(elements))

text_list = [element.text for element in elements] # list of strings
