创建一个将标识符映射到xpath查询并返回匹配标识符的函数。
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 ...
