BizTalk XSLT映射
我有两个输入csv文件，一个用于会员，一个用于福利，它们如下所示
成员xml看起来像
<Root xmlns="http://TestTwoInput.MemberSchema">
<Record xmlns="">
<EmployeeID>12</EmployeeID>
<MemberText>MEMBER</MemberText>
<SPID>007609952</SPID>
<MPID>007609952</MPID>
<SAID>12</SAID>
<ACode>05</ACode>
</Record>
<Record xmlns="">
<EmployeeID>14</EmployeeID>
<MemberText>MEMBER</MemberText>
<SPID>004482352</SPID>
<MPID>004482352</MPID>
<SAID>14</SAID>
<ACode>05</ACode>
</Record>
</Root>
好处xml看起来像
<Root xmlns="http://TestTwoInput.BenefitSchema">
<Record xmlns="">
<EmployeeID>12</EmployeeID>
<BenefitText>BENEFIT</BenefitText>
<BCode>MEA</BCode>
<ELR>001</ELR>
<Control>0100189</Control>
</Record>
<Record xmlns="">
<EmployeeID>12</EmployeeID>
<BenefitText>BENEFIT</BenefitText>
<BCode>DEN</BCode>
<ELR>002</ELR>
<Control>0100189</Control>
</Record>
<Record xmlns="">
<EmployeeID>14</EmployeeID>
<BenefitText>BENEFIT</BenefitText>
<BCode>DEN</BCode>
<ELR>002</ELR>
<Control>0100189</Control>
</Record>
<Record xmlns="">
<EmployeeID>14</EmployeeID>
<BenefitText>BENEFIT</BenefitText>
<BCode>MEA</BCode>
<ELR>001</ELR>
<Control>0100189</Control>
</Record>
<Record xmlns="">
<EmployeeID>14</EmployeeID>
<BenefitText>BENEFIT</BenefitText>
<BCode>MEA</BCode>
<ELR>001</ELR>
<Control>0100189</Control>
</Record>
<Record xmlns="">
<EmployeeID>14</EmployeeID>
<BenefitText>BENEFIT</BenefitText>
<BCode>DEN</BCode>
<ELR>002</ELR>
<Control>0100189</Control>
</Record>
</Root>
两个输入都有EmployeeID字段。我需要将这两个文件映射到一个输出，就像每个成员一样，使用其Benefit
12,MEMBER,007609952,007609952,12,05
12,BENEFIT,MEA,001,0100189
12,BENEFIT,DEN,002,0100189
14,MEMBER,004482352,004482352,14,05
14,BENEFIT,DEN,002,0100189
14,BENEFIT,MEA,001,0100189
14,BENEFIT,MEA,001,0100189
14,BENEFIT,DEN,002,0100189
这是我的地图
但这会抛出输出
12,MEMBER,007609952,007609952,12,05
12,BENEFIT,MEA,001,0100189
12,BENEFIT,DEN,002,0100189
,,,,
,,,,
,,,,
,,,,
14,MEMBER,004482352,004482352,14,05
12,BENEFIT,MEA,001,0100189
12,BENEFIT,DEN,002,0100189
,,,,
,,,,

在XSLT下面进行映射

我不确定如何通过XSLT实现输出。非常感谢任何帮助

答案 0 :(得分：1)
确定。因此，您发布的输入消息并不像aggschema格式那样，就像这样：
<Root xmlns="http://schemas.microsoft.com/BizTalk/2003/aggschema">

</Record>
<Record xmlns="">

这种情况并不真正严格要求Muenchian分组，它只需要对BizTalk不允许通过标准映射设计器的for-each（BizTalk中的循环功能）进行更多控制。如果你看一下输出XSLT，你会注意到它在嵌套for-each循环的方式以及它如何尝试测试EmployeeID节点之间的相等性方面正在做一些非感性的东西。以下是自定义XSLT的外观，正确嵌套（以及删除BizTalk生成的和不必要的变量）的方法：
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:var="http://schemas.microsoft.com/BizTalk/2003/var" exclude-result-prefixes="msxsl var s1 s0 s2 userCSharp" version="1.0" xmlns:s1="http://TestTwoInput.BenefitSchema" xmlns:ns0="http://TestTwoInput.OutputSchema" xmlns:s0="http://TestTwoInput.MemberSchema" xmlns:s2="http://schemas.microsoft.com/BizTalk/2003/aggschema" xmlns:userCSharp="http://schemas.microsoft.com/BizTalk/2003/userCSharp">
<xsl:output omit-xml-declaration="yes" indent="yes" method="xml" version="1.0" />
<xsl:template match="/">
<xsl:apply-templates select="/s2:Root" />

<xsl:template match="/s2:Root">

<xsl:for-each select="InputMessagePart_0/s0:Root/Record">

<xsl:value-of select="MPID/text()" />
</MPID>
<SIAD>
<xsl:value-of select="SAID/text()" />
</SIAD>
<ACode>
<xsl:value-of select="ACode/text()" />
</ACode>
</Member>
<xsl:variable name="empID" select="EmployeeID" />
<xsl:for-each select="../../../InputMessagePart_1/s1:Root/Record[EmployeeID = $empID]">
<Benefit>

以下是上面的XSLTransform：http://xsltransform.net/3NSSEvs
使用一些xsl:key（Muenchian分组）可能会获得更好的性能 - 如果您要在更大的文档结果集上使用它，请对此进行一些研究;但如果您的文件看起来像您通常在这里发送的文件，那么您应该没问题。说实话，如果它们变得非常大，我会建议在源代码重构事物而不是尝试使用XSLT解决所有问题 - 如果可能的话，限制生成平面文件的任何进程（如果这是来自于SQL，可能会在SQL中做更多工作） SQL实际上通过它合并一些数据和/或页面），或者用C＃编写自定义组件来处理它们比XSLT引擎更有效地合并它们最终能够做到。
