Snow XML import

I am trying to import devices into snow using snow XML import. But the output that i get from the script shows only 1 device in the xml. 

Here is the template & script that i have:

## Check for correct input parameters
if($args.Count -ne 3)
{
Write-Output "" "csv2snow.ps1" "" "Syntax:" ".\csv2snow.ps1 <path to input.csv> <output-path> <sitename>" "" "Example:" ".\csv2snow.ps1 D:\snowtemplate.csv D:\Device XML" ""
return
}
else
{
$report=$args[0]
$outputdir=$args[1]
$sitename=$args[2]

## Check that the input file exists, otherwise exit
if (!(test-path($report))) { write-host "Input file not found.";return }

## Check that the output directory exists, otherwise create it
if (test-path($outputdir)) { } else { mkdir $outputdir > $Null }

## Import the report
write-host (get-date) "Importing file.."
$myinput = import-csv $report -Delimiter ";"
$totalrows = $myinput.Length
write-host "$totalrows rows found"
$current = 0
$currhost = $myinput[$current].host
write-host $currhost
$prods = @()
$now = get-date

## Go through all rows of the CSV
while ($current -lt $totalrows) {

$h = $myinput[$current].host

if($h -ne $currhost) {

#process the old host, then start with the new data
write-host (get-date) "Processing host $currhost"

## Start writing the SnowXML for the host
$output_file = $outputdir + "\" + $currhost +'.xml'
