    Hi,

    you can do it with a few operators.

    1. Split the data attribute on \| (need to quote the | with the backslash, as Split works with regular expressions)
    2. De-pivot the resulting data_.+ attributes, resulting in a narrow table with the values from the "pivoted" split parts
    3. Aggregate using category, data to remove duplicates
    4. Aggregate using category, concatenate the data

    Example process:
    <?xml version="1.0" encoding="UTF-8"?><process version="9.8.001">
  <context>
    <input/>
    <output/>
    <macros/>
