me and someone else have already told you how to replace a substring in
a string with something else in your earlier question/posting/thread.
If you've not understood what was written there, then please ask again
and specify what specifically you're having difficulty with. If however
you've not yet looked into/tried out what we've suggested, then please
do try that first, and then come back if you have problems.
