Question

我们有一些棘手的映射要求。我正在使用BizTalk映射器在BizTalk应用程序中将传入的xml从一种形式转换为另一种形式。解决方案可以使用XSLT或内置的BizTalk functoid完成。

源架构看起来像这样：

<?xml version="1.0" encoding="utf-16"?>
<xs:schema xmlns:b="http://schemas.microsoft.com/BizTalk/2003" xmlns="http://BizTalkTestProject.SourceSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://BizTalkTestProject.SourceSchema">
    <xs:element name="Coverages">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="Coverage" maxOccurs="unbounded">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element name="Category" type="xs:string"/>
                            <xs:element name="BillingChargeType" type="xs:string"/>
                            <xs:element name="ASLCode" type="xs:string"/>
                            <xs:element name="EffectiveDate" type="xs:string"/>
                            <xs:element name="DeltaAmount" type="xs:string"/>
                        </xs:sequence>
                    </xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

目标架构如下所示：

<?xml version="1.0" encoding="utf-16"?>
<xs:schema xmlns:b="http://schemas.microsoft.com/BizTalk/2003" xmlns="http://BizTalkTestProject.DestinationSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://BizTalkTestProject.DestinationSchema">
    <xs:element name="Categories" type="CategoriesType"/>
    <xs:complexType name="CategoriesType">
        <xs:sequence>
            <xs:element name="Premium" type="CommonElementsType" maxOccurs="unbounded"/>
            <xs:element name="Tax" type="CommonElementsType" maxOccurs="unbounded"/>
            <xs:element name="Fee" type="CommonElementsType" maxOccurs="unbounded"/>
        </xs:sequence>
    </xs:complexType>
    <xs:complexType name="CommonElementsType">
        <xs:sequence>
            <xs:element name="CategoryDetail" type="CategoryDetailType" maxOccurs="unbounded"/>
        </xs:sequence>
    </xs:complexType>
    <xs:complexType name="CategoryDetailType">
        <xs:sequence>
            <xs:element name="Type" type="xs:string"/>
            <xs:element name="AnnualStatementLine" type="xs:string"/>
            <xs:element name="Amount" type="xs:string"/>
            <xs:element name="ChangeEffectiveDate" type="xs:string"/>
        </xs:sequence>
    </xs:complexType>
</xs:schema>

传入的xml数据示例：

            <AnnualStatementLine>premium ASLCode 3</AnnualStatementLine>
            <Amount>33.00</Amount>
            <ChangeEffectiveDate>2003-03-03</ChangeEffectiveDate>
        </CategoryDetail>
    </Premium>
    <Tax>
        <CategoryDetail>
            <Type>tax BillingChargeType 4</Type>
            <AnnualStatementLine>tax ASLCode 4</AnnualStatementLine>
            <Amount>44.00</Amount>
            <ChangeEffectiveDate>2004-04-04</ChangeEffectiveDate>
        </CategoryDetail>
        <CategoryDetail>
            <Type>tax BillingChargeType 5</Type>
            <AnnualStatementLine>tax ASLCode 5</AnnualStatementLine>
            <Amount>55.00</Amount>
            <ChangeEffectiveDate>2005-05-05</ChangeEffectiveDate>
        </CategoryDetail>

    <Fee>
        <CategoryDetail>
            <Type>fee BillingChargeType 6</Type>
            <AnnualStatementLine>fee ASLCode 6</AnnualStatementLine>
            <Amount>66.00</Amount>
            <ChangeEffectiveDate>2006-06-06</ChangeEffectiveDate>
        </CategoryDetail>
    </Fee>
</ns0:Categories>

映射要求是： 1.如果源xml中的Category元素具有值“Premium”，那么它应该在Categories / Premium下映射到目标。 2.如果源xml中的Category元素具有值“Tax”，那么它应该在Categories / Tax下映射到目标。 3.如果来自源xml的Category元素具有值“Fee”，那么它应该在Categories / Fee下映射到目的地。 4.输出应该只有Category，BillingChargeType，ALSCode和EffectiveDate的不同记录集。 5.输出应按类别，BillingChargeType，ALSCode和EffectiveDate

在目标节点“Amount”中具有源节点“DeltaAmount”的聚合值

在示例xml中，我已经包含了“Premium”节点的聚合示例，例如

<BillingChargeType>premium BillingChargeType 1</BillingChargeType>
<ASLCode>premium ASLCode 1</ASLCode>
<EffectiveDate>2001-01-01</EffectiveDate>

有两个Coverage记录集，其中包含3个以上的节点。这两者的区别在于

<DeltaAmount>11.00</DeltaAmount> and <DeltaAmount>5.00</DeltaAmount>

在预期输出中，您将看到只有一个与DeltaAmount node = 16映射。

我尝试使用key，distinct和generate-id与apply-templates和for-each循环在xslt中进行映射，但是没有得到我们想要的结果。所以我来这里寻求你的帮助。如果您需要更多信息，请与我们联系。

Answer 2

您可以在地图中使用全局变量，在方法上方的脚本functoid中声明列表或数组。您可以使用它来跟踪已经映射的类别。

该方法将返回一个布尔值，您可以将其连接到输出节点premium和tax。它接受类别，检查集合，如果找到则返回false，否则添加它并返回true。

System.Collections.Generic.List<string> categories;

public string AddToArray(string cat)
{
    if (categories == null)
    {
        categories = new System.Collections.Generic.List<string>();
    }

    if(!categories.Contains(cat))
    {
        categories.Add(cat);
        return true;
    }

    return false;
 }
