Extract Regex Groups directive

The EXTRACT-REGEX-GROUPS directive extracts the data from a regex group into its own column.


extract-regex-groups :column 'regex'

The directive generates additional columns based on the specified regex This ignores the $0 regex group.

Usage Notes

If multiple groups are matched, the directive creates multiple columns.

The base name of the column is appended with the match count and match position the pattern is matched for: <column>_<match-count>_<match-position>.


Using this record as an example:

{ "title": "Toy Story (1995)" }

Applying this directive:

extract-regex-groups :title [^(]+\(([0-9]{4})\).*

results in this record:

The field title_1_1 follows the format of <column>_<match-count>_<match-position>.
