I am sure that this is a straight forward application of loops, but given the lack of documentation/examples I am having some difficulty implementing.
What I want to do is populate a table of data. This first column contains the names of the items that I want to process and the column names define the operation I want to perform. Each cell evaluates a REST call constructed from the operation defined in the column header and the value in the first column.
I can read the initial table in from a CSV file, but how do I get the "names" and "operations" from the first column and row to populate the table.
If someone can point me to a good document or tutorial on loop structures in KNIME perhaps I can figure this out on my own.
I think I know what you mean, although I do not know the details and the REST call.
I think the two nodes may be helpful:
Extract Table Spec: extract Column Type and Name, which are used by the next node,
Java Snippet: you can use Column Type and Name as inputs, and a FOR loop with getCell(i,c_ColumnTy) function to retrieve cell values, and then to evalute REST call.
