Save XML nested child nodes - sql-server

Question

I have a Problem with saving the XML nodes in different Tables.
I want to save the Listnodes in one Table(ListsSet) and the Columnsnodes in another Table(ColumnsSet) which is referencing the ListTable. But in the Columnsnode is also a DependentLookupField childnode. I want to save the value from the DependentLookupField in a third Table(DependentLookupFieldsSet), which is referencing the ColumnTable.
My XML:
<Lists>
<List title="test">
<ListUrl>fsasa</ListUrl>
<ListTitle>gsdfgsg</ListTitle>
<ListDesc>jasdh</ListDesc>
<Columns>
<Column action="modify">
<InternalName>Title</InternalName>
<DisplayNameOrigin>Titel</DisplayNameOrigin>
<DisplayName>Name</DisplayName>
</Column>
<Column action="new">
<Required>true</Required>
<FieldType>Choice</FieldType>
<InternalName>anrede</InternalName>
<DisplayName>Anrede</DisplayName>
</Column>
<Column action="add" type="sitecolumn">
<Required>true</Required>
<InternalName>Bank</InternalName>
<DisplayName>Bank</DisplayName>
<MultipleValues>0</MultipleValues>
<DependentLookupFields>
<DependentLookupField internalName="Title">My Value</DependentLookupField>
</DependentLookupFields>
</Column>
</Columns>
</List>
<List>
.
.
.
etc
</List>
</Lists>
My Code of the Stored Procedure:
INSERT INTO ListsSet
SELECT
List.value('ListUrl[1]','NVARCHAR(100)') AS ListURL,
List.value('ListTitle[1]','NVARCHAR(100)') AS ListTitle,
List.value('ListDesc[1]','NVARCHAR(100)') AS ListDesc,
FROM
#xml.nodes('/Lists/List')AS TEMPTABLE(List)
INSERT INTO ColumnsSet
SELECT
l.ListsID,
c.value('FieldType[1]','NVARCHAR(100)') AS FieldType,
c.value('InternalName[1]','NVARCHAR(100)') AS InternalName,
c.value('DisplayName[1]','NVARCHAR(100)') AS DisplayName,
c.value('Required[1]','NVARCHAR(100)') AS Required,
c.value('DisplayNameOrigin[1]','NVARCHAR(100)') AS DisplayNameOrigin,
c.value('MultipleValues[1]','NVARCHAR(100)') AS MultipleValues,
FROM
ListsSet AS l
cross apply #xml.nodes('/Lists/List/Columns/Column[../../ListUrl=sql:column("l.ListUrl")]') AS TEMPTABLE(c)
INSERT INTO DependentLookupFieldsSet
SELECT
c.ColumnsID,
d.value('DependentLookupField[1]','NVARCHAR(100)') AS DependetLookupField
FROM
ColumnsSet AS c
cross apply #xml.nodes('/Lists/List/Columns/Column/DependentLookupFields/DependentLookupField[../../InternalName=sql:column("c.InternalName")]') AS TEMPTABLE(d)
The Code for saving the Listsnodes and Columnsnode is working fine. But the Code for the DependentLookupField don't save the value. In the Table "DependentLookupFieldsSet" I get the Rows which are referencing the ColumsTable(that is working), but the saved value is always null in each row.
Any help is appreciated!
