I have a string needs to be changed in a file between two values. What I want to do is if I found value A then change to value B, if I found value B then change to value A. there will be a message box popup saying that value has been changed to [xxxxx] then background picture will be also changed accordingly.
$path = c:workest.xml
$A = AAAAA
$B = BBBBB
$settings = get-content $path
$settings | % { $_.replace($A, $B) } | set-content $path
I could not figured out how to use IF
A then replace with B or IF
B then replace A. Also, the code above will delete rest of contents in the file and only save the part that I modified back to the file.
