解析xml文件並使用存儲過程獲取節點的父名稱

Question

我有一個xml文件，它是SQL Server中存儲過程的輸入。 我有一個表，其中包含列element name和parent id 。 根元素父ID為0，第一個元素父ID為1，依此類推。 我該如何實現？

我的xml中有幾種復雜的類型

<VoyageOrderMessage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="voyage.xsd">
    <MessageHeader>
            <MessageId>ID</MessageId>
            <MessageDate>2009-11-01T11:42:07.414+03:00</MessageDate>
            <MessageTypeVersion>Version</MessageTypeVersion>
            <SenderId>SI</SenderId>

                </ReceiverDetails>
    </MessageHeader>
    <VoyageOrder>

            <OrderDate>2009-11-01T11:41:59.149+03:00</OrderDate>
            <Passage>
                <PassageNumber>1</PassageNumber>
                <PassageType>Laden</PassageType>
                <DeparturePortName>Ras Laffan</DeparturePortName>
                <DeparturePortCode>RLF</DeparturePortCode>
                <DepartureTime>2009-10-06T19:06:00.000+03:00</DepartureTime>

            </Passage>

elementname parent id column
------------------------------
voyageorder   0             1
messageheader 1           2
messageid     2           3
etc

看起來您可以使用OPENXML返回的邊緣表格式。

MS SQL Server 2012架構設置 ：

查詢1 ：

declare @xml xml = '
<VoyageOrderMessage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="voyage.xsd">
    <MessageHeader>
            <MessageId>ID</MessageId>
            <MessageDate>2009-11-01T11:42:07.414+03:00</MessageDate>
    </MessageHeader>
    <VoyageOrder>
            <VoyageID>RG-FUW-001</VoyageID>
            <Amendment>4</Amendment>
            <OrderDate>2009-11-01T11:41:59.149+03:00</OrderDate>
            <Passage>
                <PassageNumber>1</PassageNumber>
                <PassageType>Laden</PassageType>
            </Passage>
    </VoyageOrder>
</VoyageOrderMessage>'

declare @idoc int

exec sp_xml_preparedocument @idoc output, @xml

select *
from openxml(@idoc, '*')

exec sp_xml_removedocument @idoc

結果 ：
