Collect Twitter user data automatically with the Get Twitter User Details Operator

Hi there,

First of all, I am RapidMiner rooky – my apologies for any stupid question in advance. I have not found an answer to my question in the community, so here I go:

I would like to analyse Tweets containing keywords using the “Search Twitter” Operator and then automatically lookup the users that posted something containing the keywords. I know the “Get Twitter User Details” Operator allows me to fill in user-ids manually (one at a time) but I would like RapidMiner to take the user-id from the “Search Twitter” Operator and do it automatically. In the Youtube Tutorial “Discover Twitter Content Using RapidMiner” (https://www.youtube.com/watch?v=ia2iV5Ws3zo), posted in another query, I learnt that a Macro might be a way to do it but I have not made it yet to read the user-ids of the “Search Twitter” results with the Macro and then pass it over to the “Get Twitter User Details” Operator. I recon, I somehow need a loop to do it. I do not expect a final, clean solution but maybe you guys have a hint. The xml code should be attached for better understanding of my problem and ideas.

Thanks very much in advance!

Julian
