Hi Adam,
It seems that the issue is the apostrophe after "L", in the wikidata
query it is "´" and the wikipedia link above
uses "'".
I see, a lof of the issues were caused by my string mishandling.
One approach you might consider is to download the entire log
history, then process it locally to filter by page
ID.
I am still unclear on how to know definitely for sure that an article was
deleted. It seems like the only way is to tell through the comments. For
example, this call:
https://en.wikipedia.org/w/api.php?action=query&list=logevents&leac…
shows the comment "[[Wikipedia:Articles for deletion/Louis Tomlinson]]"
which I have noticed to exist for other articles that were successfully
deleted, but the article "Zayn Malik" exists. The most recent event has
the comment
"[[WP:CSD#G6|G6]]: Deleted to make way for move" which would imply the
other deletions weren't successful but the article still exists.
Thanks,
Doris
