A common task for regex is to replace text that matches a pattern with a new value.
#Sample text $text = @" This is (a) sample text, this is a (sample text) "@ #Sample pattern: Text wrapped in () $pattern = '\(.*?\)' #Replace matches with: $newvalue = 'test'
-replace operator in PowerShell can be used to replace text matching a pattern with a new value using the syntax
'input' -replace 'pattern', 'newvalue'.
> $text -replace $pattern, $newvalue This is test sample text, this is a test
Replacing matches can also be done using the
Replace() method in the
[RegEx] .NET class.
