Python/Selenium 通过 xpath 查找具有特定标签、类、firstchild 的元素

Question

I need to extract elements of an HTML page, linearly (keeping true to the order of appearance) in a list. Picking elements individually - in separate lists - looks like so:

date_select = driver.find_elements(By.XPATH, "//tr[@class='dayHeader']//h5")
time_select = driver.find_elements(By.XPATH, "//span[@class='col0Item']")
class_select = driver.find_elements(By.XPATH, "//span[@class='col1Item']")
duration_select = driver.find_elements(By.XPATH, "//span[@class='col4Item']")

I've managed to get to the following:

output = driver.find_elements_by_xpath('//*[contains(@class, 'dayHeader') or contains(@class, 'col0Item') or contains(@class, 'col1Item') or contains(@class, 'col4Item')]')

But the problem is that this line has a wildcard for the tags and also doesn't take into account the firstchild for date_select. So "output" saves a lot of unwanted elements.

How can I get as precise to output all date/time/class/duration linearly, into one line?

Answer 1

I've actually managed to figure one way out:

output = driver.find_elements_by_xpath("//tr[contains(@class,'dayHeader')]//h5|//span[contains(@class,'col0Item') or contains(@class,'col1Item') or contains(@class,'col4Item')]")
