Hello,

I have to do something like this

string = " this is a good example to show"

search = array {this,good,show}

find and replace them with a token like

string = " {1} is a {2} example to {3}" (order is intact)

the string will undergo some processing and then

string = " {1} is a {2} numbers to {3}" (order is intact)

tokens are again replaced back to the string likem so that the string becomes

string = " this is a good number to show"

How should it be implemented so that the process is done at high performance ?

Thanks in advance.
