after extracting my data into in single ROW in KNIME Table,my next steps is to combine/transform them into a new table.
I check/try “Unpivoting, Cell Splitter, Column Filter, Rule Engine” but i can not find howto use “regex” by Type of the Column.
The Pattern for each Dataset is:
Integer Column - String Column [n-1] - Integer Column
The “String of Columns” have no pattern neither in count nor content, i can filter.
I am strugling to find a node(s) in Knime for resolvition it.
Do you have an ideas how todo ?
Welcome to the KNIME Community!
Can you supplement your question with an example of your current input (preferable in a workable format) and draft the expected output? At the moment it’s a bit hard to imagine what’you’re looking for.
In general, some nodes support regex based processing whenever a valid expression is used.
please find attached an example .During the pre of the workflow, i found for me too , that the structure is 100% which i described. I rebuild the workflow without the internal documents.
Is that sufficient for understanding ?
Is that really a consistant pattern you get when you read the pdf? I tried tika parser with your pdf and get inconsistent results back
I re-run the workflow with this pdf serveral times. My output is everytime the same.
The PDF is based on Template.
Otherwise the extraction is not a consistent pattern.
But back to my questions - with the regex howto use it.
Is there a Examples ?
Can these combine with Flow variables ?
Sorry for being inprecise. I meant are your columns following a consistent pattern like topic1, 1_1, 1_2,1_3, topic2, 2_1, 2_2, 2_3, …
That was not the case on my end
