如何在XML变量中获取特定元素Count

Question

考虑这个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>

我声明一个XML变量并将此XML分配给它.如何ID使用Sql Server 2008(TSQL)获取此XML变量中的元素数？

Answer 1

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

Answer 2

尝试这个：

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