有一个源xml数据，格式如下：

<Root>

	<ODH>

		<Plant>Production Plant</Plant>

		<Sloc>Storage location</Sloc>

		<PO_Number>Purchase Order number</PO_Number>

		<Order_Date>PO date</Order_Date>

	</ODH>

	<ODL>

		<PO_Line>PO line</PO_Line>

		<Material>Material number</Material>

		<Ordered_Qty>Ordered quantity</Ordered_Qty>

		<Delivery_Date>Delivery date</Delivery_Date>

	</ODL>

	<ODC>

		<PO_Line>PO line</PO_Line>

		<Seq_Num>Sequence number</Seq_Num>

		<Component>Component number</Component>

		<Req_Qty>Total component required quantity</Req_Qty>

	</ODC>

	<ODC>

		<PO_Line>PO line</PO_Line>

		<Seq_Num>Sequence number</Seq_Num>

		<Component>Component number</Component>

		<Req_Qty>Total component required quantity</Req_Qty>

	</ODC>

	<ODC>

		<PO_Line>PO line</PO_Line>

		<Seq_Num>Sequence number</Seq_Num>

		<Component>Component number</Component>

		<Req_Qty>Total component required quantity</Req_Qty>

	</ODC>

	<ODL>

		<PO_Line>PO line</PO_Line>

		<Material>Material number</Material>

		<Ordered_Qty>Ordered quantity</Ordered_Qty>

		<Delivery_Date>Delivery date</Delivery_Date>

	</ODL>

	<ODC>

		<PO_Line>PO line</PO_Line>

		<Seq_Num>Sequence number</Seq_Num>

		<Component>Component number</Component>

		<Req_Qty>Total component required quantity</Req_Qty>

	</ODC>

	<ODH>

		<Plant>Production Plant</Plant>

		<Sloc>Storage location</Sloc>

		<PO_Number>Purchase Order number</PO_Number>

		<Order_Date>PO date</Order_Date>

	</ODH>

	<ODL>

		<PO_Line>PO line</PO_Line>

		<Material>Material number</Material>

		<Ordered_Qty>Ordered quantity</Ordered_Qty>

		<Delivery_Date>Delivery date</Delivery_Date>

	</ODL>

	<ODC>

		<PO_Line>PO line</PO_Line>

		<Seq_Num>Sequence number</Seq_Num>

		<Component>Component number</Component>

		<Req_Qty>Total component required quantity</Req_Qty>

	</ODC>

	<ODC>

		<PO_Line>PO line</PO_Line>

		<Seq_Num>Sequence number</Seq_Num>

		<Component>Component number</Component>

		<Req_Qty>Total component required quantity</Req_Qty>

	</ODC>

</Root>

是订单数据，一个文件里可以有多个订单。xml数据有三种并列的节点，分别是ODH表示订单的头，ODH表示订单下的订单行，ODC表示订单的行下面的组件。数据表现为同级别的节点，但是根据顺序是有层次归属关系的，即一个ODH下面的所有ODL都是这个订单下的订单行，直到下一个ODH出现为止。一个ODL下的所有ODC都是这个订单行下的组件，直到下一个ODL或ODH出现。
现求一个XSL把这样的源xml数据转换成具有层次结构的xml数据，如下：

<Root>

	<ODH>

		<Plant>Production Plant</Plant>

		<Sloc>Storage location</Sloc>

		<PO_Number>Purchase Order number</PO_Number>

		<Order_Date>PO date</Order_Date>

		<ODL>

			<PO_Line>PO line</PO_Line>

			<Material>Material number</Material>

			<Ordered_Qty>Ordered quantity</Ordered_Qty>

			<Delivery_Date>Delivery date</Delivery_Date>

			<ODC>

				<PO_Line>PO line</PO_Line>

				<Seq_Num>Sequence number</Seq_Num>

				<Component>Component number</Component>

				<Req_Qty>Total component required quantity</Req_Qty>

			</ODC>

			<ODC>

				<PO_Line>PO line</PO_Line>

				<Seq_Num>Sequence number</Seq_Num>

				<Component>Component number</Component>

				<Req_Qty>Total component required quantity</Req_Qty>

			</ODC>

		</ODL>

	</ODH>

	<ODH>

		<Plant>Production Plant</Plant>

		<Sloc>Storage location</Sloc>

		<PO_Number>Purchase Order number</PO_Number>

		<Order_Date>PO date</Order_Date>

		<ODL>

			<PO_Line>PO line</PO_Line>

			<Material>Material number</Material>

			<Ordered_Qty>Ordered quantity</Ordered_Qty>

			<Delivery_Date>Delivery date</Delivery_Date>

			<ODC>

				<PO_Line>PO line</PO_Line>

				<Seq_Num>Sequence number</Seq_Num>

				<Component>Component number</Component>

				<Req_Qty>Total component required quantity</Req_Qty>

			</ODC>

			<ODC>

				<PO_Line>PO line</PO_Line>

				<Seq_Num>Sequence number</Seq_Num>

				<Component>Component number</Component>

				<Req_Qty>Total component required quantity</Req_Qty>

			</ODC>

		</ODL>

	</ODH>

</Root>
