Replace

Syntax

	$pattern.regexReplace($text, $replacement)

Description

Replaces the occurrences of the given pattern in the given text with the given replacement. The replacement can be either a string or a function.

If the replacement is a string, every search hit in the given text will be replaced by the given replacement string.

If the replacement string contains back references ($1, $2,...), they are replaced with the text hit by the referenced group.

If the replacement is a function, it is called with each search hit and generates a dynamic replacement text. The return value of the function can also contain back references.

Parameters

Name Type Description Mandatory Default
pattern Business object The regex pattern to use to search for the string to replace. yes
text String The text by which to search for matching search hits to replace. yes
replacement String/Function Specifies how the search hits should be replaced. yes

Return value

Type: String

The text in which all search hits were replaced.

Examples

Simple replace

	regex("a(b+)").regexReplace("XXXabbbYYY", "_")

Output: XXX_YY

The only search hit "abbb" is replaced with a "_".

Replace with reference

	regex("a(b+)").regexReplace("XXXabbbYYY", "_$1_")

Output: XXX_bbb_YY

The reference $1 refers to the first group (b+). The search hit "abbb" is replaced by the content of the group "bbb", which is additionally enclosed by "_".

Replace with function

	regex("a(b+)").regexReplace("XXXabbbYYY", m -> $m.regexGroup(1).length())

Output: XXX3YY

The search hit "abbb" is replaced by the length of the first group (b+), which equals 3.
