Question

我正在处理非结构化XML文档，以便将其转换为结构化文档。非结构化文档如下所示

<?xml version="1.0" encoding="UTF-8"?>
 <CustomerInformation>
    <CustomerPurchaseID>String</CustomerPurchaseID>
    <MemberAddress>String</MemberAddress>
    <MemberID>String</MemberID>
    <MemberCity>String</MemberCity>
    <MemberName>String</MemberName>
    <MemberType>String</MemberType>
    <MemberState>String</MemberState>
    <MemberSince>String</MemberSince>
    <PurchaseDate>String</PurchaseDate>
    <CreditCardName></CreditCardName>
    <CreditCardExpirration></CreditCardExpirration>
    <Orders>
        <LineItemCode>String</LineItemCode>
        <LineItemID>String</LineItemID>
        <LineItemDescription>String</LineItemDescription>
        <DiscountCode>String</DiscountCode>
    </Orders>
    <Orders>
        <LineItemCode>String</LineItemCode>
        <LineItemID>String</LineItemID>
        <LineItemDescription>String</LineItemDescription>
        <DiscountCode>String</DiscountCode>
    </Orders>
    <ShipToAddress>String</ShipToAddress>
    <ShipToCity>String</ShipToCity>
    <ShipToFirstName>String</ShipToFirstName>
    <ShipToLastName>String</ShipToLastName>
    <ShipToState>String</ShipToState>
    <ShipToZIPCode>String</ShipToZIPCode>
    <CustomerAddressLine1>String</CustomerAddressLine1>
    <CustomerAddressLine2>String</CustomerAddressLine2>
    <CustomerID>String</CustomerID>
    <CustomerCity>String</CustomerCity>
    <CustomerEmail>String</CustomerEmail>
    <CustomerFirstName>String</CustomerFirstName>
    <CustomerLastName>String</CustomerLastName>
    <CustomerHomePhone>String</CustomerHomePhone>
    <CustomerState>String</CustomerState>
    <CustomerZIP>String</CustomerZIP>
    <Status>String</Status>
    <OrderedFromName>String</OrderedFromName>
    <CustomerIdentification></CustomerIdentification>
    <PrimaryCustomerIndicator>String</PrimaryCustomerIndicator>
    <OrderedFromAddressLine1Text>String</OrderedFromAddressLine1Text>
    <OrderedFromAddressLine2Text>String</OrderedFromAddressLine2Text>
    <OrderedFromCityName>String</OrderedFromCityName>
    <OrderedFromStateCode>String</OrderedFromStateCode>
    <OrderedFromZip5Code>String</OrderedFromZip5Code>
    <OrderedFromZip4Code>String</OrderedFromZip4Code>
   </CustomerInformation>

将其转换为以下内容：

<?xml version="1.0" encoding="UTF-8"?>

            <AddressLine1Text>String</AddressLine1Text>
            <AddressLine2Text>String</AddressLine2Text>

        </ShippingAddress>
        <LineItem>
            <LineItemNumber>String</LineItemNumber>
            <LineItemQuantityCount>0</LineItemQuantityCount>
            <ItemOrderedIndicator>String</ItemOrderedIndicator>
            <Discount>String</Discount>

我能够通过创建结构化格式生成XML，并通过简单地使用下面的XSLT节点值来提取相关字段：

<xsl:value-of select=.../>

然而，我觉得可能有更好的方法来做到这一点。我希望能够在导航非结构化或平面文档时控制结构的生成方式。例如，有没有办法对所有MemberAddress字段的元素进行分组？如果我能够这样做，我可以创建输出的成员部分。我也可以为其他元素做同样的事情。我对结构化文档进行硬编码的担忧是它将来可能会发生变化。如果可能的话，我更愿意控制输出。源文档中的所有成员信息应映射到目标文档中的成员元素。源文档中以OrderedFrom开头的元素应映射到目标文档中的Company字段。反过来，ShipTo元素应映射到目标文档的订单部分中的出货信息，依此类推。请帮忙!!

我对结构化文档进行硬编码的担心是它可能改变未来。

XSLT样式表将数据从一个XML模式转换为另一个XML模式。期望任一模式中的更改都不需要重写样式表是不现实的。

有没有办法为所有MemberAddress字段分组元素示例

是的，如果你有办法识别它们。例如，你可以这样做：

<Member>
    <xsl:for-each select="*[starts-with(name(), 'Member')]">
        <xsl:element name="{substring-after(name(), 'Member')}">
            <xsl:value-of select="." />
        </xsl:element>
    </xsl:for-each>
</Member>

得到：

<Member>
    <Address>String</Address>
    <ID>String</ID>
    <City>String</City>
    <Name>String</Name>
    <Type>String</Type>
    <State>String</State>
    <Since>String</Since>
</Member>

但这不符合您的预期输出。顺便说一句，您的输出显示了很多输入中没有的数据，例如会员的电子邮件。
