How to get specific element Count in XML variable

Question

Consider this XML:

<Employees>
    <Person>
        <ID>1000</ID>
        <Name>Nima</Name>
        <LName>Agha</LName>
    </Person>
    <Person>
        <ID>1001</ID>
        <Name>Ligha</Name>
        <LName>Ligha</LName>
    </Person>
    <Person>
        <ID>1002</ID>
        <Name>Jigha</Name>
        <LName>Jigha</LName>
    </Person>
    <Person>
        <ID>1003</ID>
        <Name>Aba</Name>
        <LName>Aba</LName>
    </Person>
</Employees>

I declare a XML variable and assign this XML to that. How I can get count of ID elements in this XML variable using Sql Server 2008 (TSQL)?

Answer 1

SELECT @XMLVariable.value('count(/Employees/Person/ID)', 'int') AS IDCount

Answer 2

try this:

declare @xmlvar XML;
set @xmlvar ='<YOUR XML>';
select @xmlvar.value('count(/Employees/Person/ID)', 'INT') AS 'Count'
