愈來愈常見到這種寫法，常遇到 <button> 的 tag, 要判斷有沒有 class 屬性裡有沒有 “selected” 這一個值。
解法1:
driver.find_elements(By.XPATH, '//button[contains(@class, "selected")]')
解法2: 把 element 的 attribute 取出來判斷。
button_cass = str(el_time_picker.get_attribute('class'))
if "selected" in button_cass:
This selector should work but will be more efficient if you replace it with your suited markup:
//*[contains(@class, 'Test')]
Or, since we know the sought element is a div:
//div[contains(@class, 'Test')]
But since this will also match cases like class="Testvalue" or class="newTest", @Tomalak’s version provided in the comments is better:
//div[contains(concat(' ', @class, ' '), ' Test ')]
If you wished to be really certain that it will match correctly, you could also use the normalize-space function to clean up stray whitespace characters around the class name (as mentioned by @Terry):
//div[contains(concat(' ', normalize-space(@class), ' '), ' Test ')]
Note that in all these versions, the * should best be replaced by whatever element name you actually wish to match, unless you wish to search each and every element in the document for the given condition.
說明：之所以要寫這麼複雜，是因為 1foo, foo, foo2, 如果只有使用 contains ‘foo’ 這3個都會被選到，預期只想選 ‘foo’ 的話要寫的複雜才能取得。
