    [xml]$x = get-content $f

    $top = $x.firstchild

    $m += $top.innerxml 

  }

  $m += "</" + $root + ">"

  [xml]$x = $m

  $x.save($out)

}

function merge ($out, $xmls) {
$m = ""

$root = "unknown"
foreach ($f in $xmls){
[xml]$x = get-content $f
$top = $x.firstchild

$root = $top.name
$m += $top.innerxml
}
$m += "</" + $root + ">"
[xml]$x =  "<" + $root + ">" + $m
$x.save($out)
