Removing extranious data from a string @{Name=WEBHOST001-OI3w}

depends a bit on how you are getting the string that you want to split as has been mentioned elsewhere but you could most easily use ConvertFrom-StringData

$string = "Name=WEBHOST001-OI3w"
$converted = ConvertFrom-StringData $string
$NameValue = $converted['Name']
Write-Output $NameValue
