I had thought that -replace only did the first item. I'll have to look at other things and remember while i abandoned the built in -match and -replace and went to dotnet methods. There was a reason but i must have remembered it falsely. Thanks guys lol, i can’t believe i didn’t know that. I had thought that -replace only did the first item.

Thanks. BTW, the particular task you were doing could be accomplished without custom code: $example -replace 'wiki://(\d+)_(\d+)','$1/$2/index.html' But there are some cases where the regex could be simplified by using code to assist in the processing.
