This node has exactly the same functionality as the Row Filter node,
except for that it has an additional output that provides the rows that are
filtered out. For performance and disk space reasons you may want to consider
using the Row Filter node. The table at the upper port (with index 0) contains the
rows included in the result according to the filter criteria (the node settings).
The lower port (with index 1) provides a table with all rows not matching
the filter criteria. The sum of the number of rows in the two output tables
is the same than the number of rows in the input table.
Following is a copy of the node description of the Row Filter node:
The node allows for row filtering according to certain criteria. It can include or exclude: certain ranges (by row number), rows with a certain row ID, and rows with a certain value in a selectable column (attribute). Below are the steps on how to configure the node in its configuration dialog. Note: The node doesn't change the domain of the data table. I. e. the upper and lower bounds or the possible values in the table spec are not adapted, even if one of the bounds or one value is fully filtered out.
^foo.*" matches anything that starts with "foo". The '^'-character stands for the beginning of the word, the dot matches any (one) character, and the asterisk allows any number (including zero) of the previous character.
[0-9]*" matches any string of digits (including the empty string). The
]define a set of characters (they could be added individually like
, or by range). This set matches any (one) character included in the set.
