PowerShell - Search XML by passing an input parameter

In this script I would like to show how we can perform XML search by passing an input parameter.
Sample xml file to work with the example

1. <Employees>  
2. <Employee>  
3.   <Name>TestName</Name>  
4.   <Age>32</Age>  
5.   <Location>Hyderabad</Location>  
6. </Employee>  
7. <Employee>  
8.   <Name>TestName1</Name>  
9.   <Age>29</Age>  
10.   <Location>Hyderabad</Location>  
11. </Employee>  
12. <Employee>  
13.   <Name>TestName3</Name>  
14.   <Age>45</Age>  
15.   <Location>Rajahmundry</Location>  
16. </Employee>  
17. </Employees> 

Power shell script 

1. cls  
2. function XmlOperations  
3. {  
4.    param (  
5.         [Parameter(Mandatory)]  
6.         [string] $EmployeeName  
7.     )  
8.   
9.     $xml = [xml](Get-Content C:\sample.xml)  
10.     $xml.Employees.Employee | where { $_.Name -like "*$EmployeeName*" }  
11. }
