Wlan Import ps1

I have a directory and exported all wlan's to .xml and at the moment import via .bat file, how do I get them to import using the following script
Please can someone help me out here Where in this script do I show the directory holding the .xml files that need to be imported.
I don't need the export part just need the import part. [That's why I commented it out]

.DESCRIPTION 
Exports all-user WLAN profiles to Xml-files to the specified directory using netsh.exe 
.PARAMETER XmlDirectory 
Directory to export Xml configuration-files to 
.EXAMPLE 
Export-WLAN -XmlDirectory c:\temp\wlan 
 
 
[CmdletBinding()] 
 param ( 
 [parameter(Mandatory=$true)] 
 [string]$XmlDirectory 
 ) 
 
#Export all WLAN profiles to specified directory 
$wlans = netsh wlan show profiles | Select-String -Pattern "All User Profile" | Foreach-Object {$_.ToString()} 
$exportdata = $wlans | Foreach-Object {$_.Replace("    All User Profile     : ",$null)} 
$exportdata | ForEach-Object {netsh wlan export profile $_ $XmlDirectory key=clear} 
}

function Import-WLAN { 
<# 
.SYNOPSIS 
Imports all-user WLAN profiles based on Xml-files in the specified directory 
.DESCRIPTION 
Imports all-user WLAN profiles based on Xml-files in the specified directory using netsh.exe 
.PARAMETER XmlDirectory 
Directory to import Xml configuration-files from 
.EXAMPLE 
Import-WLAN -XmlDirectory c:\temp\wlan 
#> 
 
[CmdletBinding()] 
 param ( 
 [parameter(Mandatory=$true)] 
 [string]$XmlDirectory 
 ) 
 
#Import all WLAN Xml-files from specified directory 
Get-ChildItem $XmlDirectory | Where-Object {$_.extension -eq ".xml"} | ForEach-Object {netsh wlan add profile filename=($XmlDirectory+"\"+$_.name)} 
}

 

If I run the code below it imports the xml files.
 

 $XmlDirectory='\\server\share\wireless'
#Import all WLAN Xml-files from specified directory 
Get-ChildItem $XmlDirectory | Where-Object {$_.extension -eq ".xml"} | ForEach-Object {netsh wlan add profile filename=($XmlDirectory+"\"+$_.name)} 

 
 
Now how do I add all of the following

 netsh wlan add  filter permission=block ssid="SomeSSID" networktype=infrastructure
 netsh wlan add filter permission=block ssid="SomeSSID"  networktype=infrastructure
 netsh wlan add filter permission=block ssid="SomeSSID"  networktype=infrastructure
