使用 find_elements 时列表没有属性文本

Question

I am scraping the xbox website to get some account information. In the information, I am trying to scrape someone's name and their status, which fall under the same tag and class, so I made a list to append each of these values to. However, the account does not always have a name attached to it, but always a status so I made an if statement to tell whether there is more than 1 element scraped. However, it only works if there are two elements; not one.

status_name = driver.find_elements_by_xpath("//div[contains(@id,'right-side')]/p")

  statusName = []

  if len(status_name) > 1:
    for r in status_name:
      statusName.append(r.text)
    status = statusName[1]
    irlname = statusName[0]
  else:
    status=statusName.text

File "main.py", line 286, in xbox
    statusName.append(status_name.text)
AttributeError: 'list' object has no attribute 'text'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/opt/virtualenvs/python3/lib/python3.8/site-packages/discord/ext/commands/bot.py", line 939, in invoke

elements (with s ) always return list - even for one element - and you don't have to use len() - it will always iterate list, not chars.

BTW: if it can't find elements then it gives empty list and you don't need len() too.

status_name = driver.find_elements_by_xpath("//div[contains(@id,'right-side')]/p")

statusName = []

for r in status_name:
    statusName.append(r.text)

or shorter

status_name = driver.find_elements_by_xpath("//div[contains(@id,'right-side')]/p")

statusName = [r.text for r in status_name]

EDIT:

You need len() after getting text - to see if it has name

if len(statusName) > 1:
    status  = statusName[1]
    irlname = statusName[0]
else:
    status  = statusName[0]
    irlname = '???'

Eventually you can write all in your way but it will aways need indexes. And you can do it without list statusName

status_name = driver.find_elements_by_xpath("//div[contains(@id,'right-side')]/p")

if len(status_name) > 1:
    status  = status_name[1].text
    irlname = status_name[0].text
else:
    status  = status_name[0].text
    irlname = '???'
