The "find_elements_by_xpath" likely gives you a list of elements
on the *initial* page. The "for" sets things up that this list
is iterated over.

This "click" may change the page which means that
you would now be on a page different from the initial page.

It is likely that your web access framework contains some form
of automatic garbage collection: when you switch to a new page,
references to the old page may become stale.

This could explain that you sometimes observe a
"StaleElementReferenceException".


Read the documentation of your web access framework to find
out whether you can control stalelifying of elements when you
switch a page.

If this is impossible, avoid accessing elements of a page
once you have switched to a new page. To this end, extract (and store)
all relevant information from the page before you switch to a new one
and, if necessary, use the extracted information to later restore
the previous page state.


As you can see from my explanation: your question is much more
related to your web access framework than to Python in general.

Likely, there is a forum (dedicated to this framework)
that can better help you with this question than this general
Python list.
