I tried, but I am unable to use them directly. The thing is the data 'title' gets extracted twice for more than one users because of the loop. I want to restrict the loop to extract elements like title, PMID and list of authors only once. And I want to do it while I am extracting it. It seems that I can remove the duplicates later but, it all messes up. Because there are some users and tags that are duplicates too, but I want them. Can you help please.
