Count Specific Node in XML using SQL

I'm going to explain an example to find the node from an XML file using SQL Server

declare @xml-var  XML;
set @xml-var [email protected];
select @[email protected]('count(/courses/course)', 'INT')

In the above example,

@Result is an XML file, where we find the nodes.

@xml-var is an XML type variable.

Here XML file look like this...

<?xml version="1.01" encoding="ISO-55-4"?>
-<courses>
 - <course>
       <ID>1</ID>
       <COURSENAME>MCA</COURSENAME>
       <YEARS>2009</YEARS>
       <body>Something here,,,,,,!</body>
   </course>
 - <course>
       <ID>2</ID>
       <COURSENAME>MBA</COURSENAME>
       <YEARS>2011</YEARS>
       <body>Something here,,,,,,!</body>
   </course>
 - <course>
       <ID>3</ID>
       <COURSENAME>B.Tech.</COURSENAME>
       <YEARS>1999</YEARS>
