Regex Search String

When you select the regex search string transformer, you can use a subset of Python's re library as an output processor.

The action types supported are the following.

Scans through the string looking for the first location where this regular expression produces a match, and returns a corresponding match object.

In the above example, you can see 'dag_id' as part of the search string that the regex pattern is set to search.

When the script is run with the settings above, the output is as follows.


If zero or more characters at the beginning of the string match this regular expression, returns a corresponding match object.


Returns the string obtained by replacing the occurrence of a pattern in a string by the replacement string.
