save multiple records from xml column to multiple rows in db table

[sasha3]

From my C# code i execute following SP, to save the xml file into a table.
I would like to save a row in my table for each ComponentModule element.

<ComponentModules>
    <ComponentModule ComponentModuleID="5"/>
    <ComponentModule ComponentModuleID="6"/>
</ComponentModules>

Now i have something like this in my db table:

ID ComponentNo Lenght ComponentModule ID
1 2 3 5

What i want is:
ID ComponentNo Lenght ComponentModule ID
1 2 3 5
1 2 3 6


My SP to save xml data in Components table:

CREATE PROCEDURE [dbo].[insert_Components_XML]
@XMLproductDoc xml
AS
BEGIN
SET NOCOUNT ON;
insert into Components (ID,ComponentNo,Length,ComponentModule)
SELECT x.y.value('@ID','varchar(30)'),
x.y.value('@ComponentNo','varchar(30)'),
x.y.value('@Length','varchar(30)'),
x.y.value('(./ComponentModules//ComponentModule//@ComponentModuleID [1]','varchar(30)')
FROM @XMLproductDoc.nodes('/Product/ProductDetails/Components/Component') AS x(y)
END

XML structure is something like this:

<Product atr1="1" atr2="2" atr3="3">
<ProductDetails atribute="1" atribute2="2">
<someother>
</someother>
<Components ID="name">
    <Component ID="1" ComponentNo="2" Length="3">
        <ComponentModules>
            <ComponentModule ComponentModuleID="5"/>
            <ComponentModule ComponentModuleID="6"/>
        </ComponentModules>
    </Component>
</Components>
</ProductDetails>
</Product>

Thanks in advance!
