webdriver wait for one of a multiple elements to appear

Question

Is there a way to get a webDriverWait to wait for one of a number of elements to appear and to act accordingly based on which element appears?

At the moment

Answer 1

Create a function that takes a map of identifiers to xpath queries and returns the identifier that was matched.

def wait_for_one(self, elements):
    self.waitForElement("|".join(elements.values())
    for (key, value) in elements.iteritems():
        try:
            self.driver.find_element_by_xpath(value)
        except NoSuchElementException:
            pass
        else:
            return key

def othermethod(self):

    found = self.wait_for_one({
        "mime": "//a[contains(text(), '%s')]",
        "exists_error": "//li[contains(text(), 'That file already exists')]"
    })

    if found == 'mime':
        do stuff ...
    elif found == 'exists_error':
        do other stuff ...
