Capture processes values by capturing new values using regular expressions.

Interpretation Methods

The processor supports these interpretation methods:

object
data

Options

Field	Type	Description	Required
expression	string	the regular expression used to capture new values.	Yes
type	string	determines which regular expression function is applied. must be one of: - find: applies the `Find(String)?Submatch` function - find_all: applies the `FindAll(String)?Submatch` function - named_group: applies the `Find(String)?Submatch` function and stores new values as objects using subexpressions	Yes
count	integer	manages the number of repeated capture groups. defaults to match all capture groups.	No

Use Cases

Creating New Objects

If the named_group type is used, then captured values are returned as a new object. For example, if the named_group expression is (?P<a>[a-zA-Z]+) (?P<c>[a-zA-Z]+), then the result is:

b d

{"a":"b","c":"d"}
