Find and click an item from 'onclick' partial value

Either XPath or CssSelector would do. No need to have any looping, but straightforward locators.

driver.find_element_by_xpath(".//input[contains(@onclick, '1 Bedroom Deluxe')]")driver.find_element_by_css_selector("input[onclick*='1 Bedroom Deluxe']")

You are on the right track!

buttons = driver.find_elements_by_name('booksubmit')for button in buttons:

Yes, this exactly. You want to iterate through name = booksubmit elements and check the "onclick" attribute of each one. Here's what the rest would look like:

buttons = driver.find_elements_by_name('booksubmit')for button in buttons:    onclick_text = button.get_attribute('onclick')    if onclick_text and re.search('Bedroom Deluxe', onclick_text):        print "found it!"        button.click()

BeautifulSoup does not help much in this case, since you still need to use selenium's methods to get ahold of the element to click on.

A general answer for solving these kinds of problems is using the Selenium IDE. From here, you can manually click buttons on a website and have the Selenium IDE (a Firefox plugin) record your actions. From there you can File > Export Test Case As... and choose whatever coding language you want.

EDIT: Sometimes you might actually be finding the correct element, but the webdriver tries to find it before it's there. Try adding this line after you create your webdriver:
In Python:
driver.implicitly_wait(10)

This tells your webdriver to give itself more time to try to find the object. It does not add a 10 second wait, but says keep looking for 10 seconds. If it finds the element before 10 seconds, it will continue on as normal.
