how to find "whatever" string lenght and replace

[marcorocchini]

Hi Cats,

I need to find a string in a input.txt file

Current Playback Device ID=2A99FA92-E624-4650-A032-DA719D9B03D5

and replace it with:

Current Playback Device ID=721D0FD1-DD46-11d0-8AAC-00A0C91D299F

BUT consider that the replace have to be also in the case that the original string - in this case Current Playback Device ID=2A99FA92-E624-4650-A032-DA719D9B03D5 - contains different chatacters

for example Current Playback Device ID=AAAAAAAA-E624-AAAA-A032-AAAAAAAAAAAA

How can I do?
thanks

Strictly speaking, you cannot.

But if I am correctly reading between the lines, you need to use the LEN() - length, and MID() - middle position, string functions.

Use regex. Search:

Current Playback Device ID=[0-9A-F]{8}-E624-[0-9A-F]{4}-A032-[0-9A-F]{12}

Replace:

Current Playback Device ID=721D0FD1-DD46-11d0-8AAC-00A0C91D299F

You can also use CMD's findstr which allows wild cards, place holders and many options. This can be used in a batch file as well for automating replacement.
