StaleElementReferenceError를주는 요소는 무엇입니까?

Question

그래서 내 코드는 나에게주고있다 [remote server] resource://fxdriver/modules/web-element-cache.js:8325:24:in `fxdriver.cache.getElementAt': Element is no longer attached to the DOM (Selenium::WebDriver::Error::StaleElementReferenceError)

이 코드에서 사용되는 여러 가지 요소가 있으며, 나는 그것을 위해 wait이 있는지 확인 할 수 있도록 나에게 오류를 제공하는 요소를 참조하는 것을 시도하고있다. 오류의 전체 스택 추적, 그것은 예외를 던졌다 정확한 라인을 가리 것이다

path = [".//*[@id='sub_nav_content']/table/tbody/tr[2]/td[3]/a", ".//*[@id='sub_nav_content']/table/tbody/tr[3]/td[3]/a", ".//*[@id='sub_nav_content']/table/tbody/tr[4]/td[3]/a", ".//*[@id='sub_nav_content']/table/tbody/tr[5]/td[3]/a", ".//*[@id='sub_nav_content']/table/tbody/tr[6]/td[3]/a", ".//*[@id='sub_nav_content']/table/tbody/tr[7]/td[3]/a", ".//*[@id='sub_nav_content']/table/tbody/tr[8]/td[3]/a", ".//*[@id='sub_nav_content']/table/tbody/tr[9]/td[3]/a", ".//*[@id='sub_nav_content']/table/tbody/tr[10]/td[3]/a", ".//*[@id='sub_nav_content']/table/tbody/tr[11]/td[3]/a"]
