$weburl = $DocURL 
 
while ($webfound -eq $false) { 
    if ($weburl.Contains("/")){ 
    $weburl = $weburl.Substring(0,$weburl.LastIndexOf("/")) 
    $web = get-spweb -identity $weburl -ea 0 
    if ($web -ne $null){ 
        $webfound = $true 
    } 
    }else{ 
    Write-Host -ForegroundColor Red "The Web could not be found" 
    return -1 
    } 
     
} 
$web.GetFile($DocURL).item.xml.Replace("' ", "' `n").Replace("`" ", "`" `n")
