python selenium click on button

Question

I am quite new to python selenium and I am trying to click on a button which has the following html structure:

<div class="b_div">      <div class="button c_button s_button" onclick="submitForm('mTF')">         <input class="very_small" type="button"></input>         <div class="s_image"></div>         <span>            Search         </span>     </div>      <div class="button c_button s_button" onclick="submitForm('rMTF')" style="margin-bottom: 30px;">         <input class="v_small" type="button"></input>         <span>               Reset         </span>    </div>  </div> 

I would like to be able to click both the Search and Reset buttons above (obviously individually).

I have tried a couple of things, for example:

driver.find_element_by_css_selector('.button .c_button .s_button').click() 

or,

driver.find_element_by_name('s_image').click() 

or,

driver.find_element_by_class_name('s_image').click() 

but, I seem to always end up with NoSuchElementException, for example:

selenium.common.exceptions.NoSuchElementException: Message: u'Unable to locate element: {"method":"name","selector":"s_image"}' ; 

I am wondering if I can somehow use the onclick attributes of the HTML to make selenium click?

Any thoughts which can point me in the right direction would be great. Thanks.

Answer 1

Remove space between classes in css selector:

driver.find_element_by_css_selector('.button .c_button .s_button').click() #                                           ^         ^ 

=>

driver.find_element_by_css_selector('.button.c_button.s_button').click()

try this:

download firefox, add the plugin "firebug" and "firepath"; after install them go to your webpage, start firebug and find the xpath of the element, it unique in the page so you can't make any mistake.

See picture:

browser.find_element_by_xpath('just copy and paste the Xpath').click()
