Powershell: using -replace with regular expression

Question

How can I use a regular expression to replace any text between quotes for a -replace statement? I can get it to work with static text, but it could be virtually any text.

Example:

$filecontent -replace 'AssemblyCopyright("text")', 'AssemblyCopyright("Copyright © 2016 myCompany")' | Out-File $file

given the AssemblyCopyright("text") could actually be anything including blank

AssemblyCopyright("")

Try it like this

... -replace 'AssemblyCopyright\("[^"]*"\)', 'AssemblyCopyright("Copyright © 2016 myCompany")'

Please note however, that this will assume that the text within the quotes does not contain another quote.

That's a lot closer that I have gotten. The only problem is there's an A character in front of the copyright. I think regex or powershell does NOT like the copyright symbol

I think that is an encoding issue on your side - I did a quick test within PoSh ISE with no issues - please see the GIF
