Filtering collection with criteria

I am on a quest to retrieve useful data from PDF.

I already conquered the first battle with the Table Extraction extension. I am now faced with another challenge:

How do I filter out a collection? Let's say I want to ignore examplesets with less than 10 examples in a collection and output a collection of al the other examplesets. How can I go about going that?

    Hi @pblack476,

    try the Loop Collection operator. 
    In each loop execution you'll get one example set. You can then use for example Extract Macro to determine the number of examples, and conditionally return the example set or not.

    Oh wow. I did not know the branch operator could have empty connections inside. That solves it. I was trying to do just that but it was getting really complex to filter out the "else" examples out.

    Thanks to both of you!
