Noob Powershell String Parsing Question

I am very new to Powershell and am trying to solve what appears to be a very simple problem.I have a variable called $TestLocationsThe value of $TestLocations is:[code="plain"]xxx----------2234465[/code]I need to extract the values of Lines 3,4,5 & 6 and assign their values to an array. E.g. if I had an array called #x it would look like this:#x = @((2),(23),(44),(65))
