Swapping Strings Using Regex
#Given Name : Chendrayan Venkatesan
#Required Output: Venkatesan , Chendrayan
"Chendrayan Venkatesan" -replace "([a-z]+)\s([a-z]+)" ,'$2, $1' |
|
Explanation: ([a-z]+) captures a-z characters in the string ans \s is for white space. $2 is result of second captured value [Venkatesan] and $1 is for the first value [Chendrayan]
Removing Digits from String
#Given Name : Chendrayan12345 Venkatesan
#Required Output: Chendrayan Venkatesan
'Chendrayan12345 Venkatesan' -replace "\d+" |
