How to select input element with Python Selenium

Question

I just cannot find working way to select this element, tried by CSS and xpath, but nothing works.

<input type="submit" value="Submit">

This does not work:

driver.find_element_by_xpath("//*[@id='theform']/div[2]/input").click()
driver.find_element_by_css_selector(".submit[value='Submit']").click()

Answer 1

This does not work:

driver.find_element_by_xpath("//*[@id='theform']/div[2]/input").click() driver.find_element_by_css_selector(".submit[value='Submit']").click()

The first invocation likely does not work because the input descendant node is most likely too vague and ambiguous.

The second invocation doesn't work because .submit[value='Submit'] is searching for (in english)

Any element that has class~="submit" AND value="Submit"

The value attribute matches, but not the class selector.

You could find that element with a quick CSS selector:

driver.find_element_by_css_selector("input[type='submit']")

See Effective CSS Selectors to see how to formulate good CSS selectors, and why this selector above would work.
