Sed equivalent in Powershell

A few days back I was trying to fix some issues with our Visual Studio solution, where the hintpaths were all wrong, so I thought it would try to use PowerShell:
ls -recurse -Include *.csproj | % {sp $_ isreadonly $false; (Get-Content $_) -replace "here","there" | Set-Content -Path $_}
A few comments to make:

% is an alias for foreach-object
sp is an alias fro Set-ItemProperty
-replace allows using regular expressions

The only downside was that I still had to check in the projects back into TFS manually, for some reason the TFS powertools would not allow me to checkout more than 2 projects at the same time, but on the plus side this is a good equivalent to Sed in PowerShell.
