XML Values to retrieve in single Column with Any(,) Delimiter (2) - sql-server

Question

declare #x xml =
'<Detials xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Tests>
<Test Name="Test1" TotalMarks="100">95</Test>
<Test Name="Test2" TotalMarks="200">65</Test>
<Test Name="Test3" TotalMarks="150">95</Test>
<Test Name="Test4" TotalMarks="150"></Test>
</Tests>
<Tests>
<Test Name="Test1" TotalMarks="100">95</Test>
<Test Name="Test2" TotalMarks="200">65</Test>
<Test Name="Test3" TotalMarks="150">95</Test>
<Test Name="Test4" TotalMarks="150"></Test>
</Tests>
</Detials>'
When i queried like this
SELECT STUFF(
#x.query('for $a in (*:Detials/Tests/Test/#Name)
return <a>{concat(",", $a)}</a>')
.value('.', 'NVARCHAR(MAX)'),
1, 1, '') AS ListOfName
I get like this
ListofName
Test1,Test2,Test3,Test4,Test1,Test2,Test3,Test4
But Want to shred the xml based on the <Test> Which can give the result like this below
ListofName
Test1,Test2,Test3,Test4
Test1,Test2,Test3,Test4
Please help me here to shred original XML into separate rows before string concatenation with query() and value()
Thanks in Advance ,Jayendran

Try this solution:
declare #x xml =
'<Detials xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Tests>
<Test Name="Test1" TotalMarks="100">95</Test>
<Test Name="Test2" TotalMarks="200">65</Test>
<Test Name="Test3" TotalMarks="150">95</Test>
<Test Name="Test4" TotalMarks="150"></Test>
</Tests>
<Tests>
<Test Name="Test1" TotalMarks="100">95</Test>
<Test Name="Test2" TotalMarks="200">65</Test>
<Test Name="Test3" TotalMarks="150">95</Test>
<Test Name="Test4" TotalMarks="150"></Test>
</Tests>
</Detials>'
-- Edit 1
SELECT XmlTable.OriginalID, ROW_NUMBER() OVER(ORDER BY x.XmlCol) AS RowNum, y.ListOfName
FROM (SELECT 1 AS OriginalID, #x AS XmlCol) AS XmlTable -- Edit 2
CROSS APPLY XMLTable.XmlCol.nodes('*:Detials/Tests') AS x(XmlCol)
CROSS APPLY(
SELECT STUFF(x.XmlCol.query('for $a in (Test/#Name) return <a>{concat(",", $a)}</a>').value('.', 'NVARCHAR(MAX)'), 1, 1, '')
) AS y(ListOfName)
