问题描述

Below is the input message :以下是输入消息：

Input:输入：

Record Name : Member
Fields: Company Name , Person Name , State , Country , Amount , CombinedState

This is my input XML:这是我的输入 XML：

<ns0:Root xmlns:ns0="Test">

The requirement is:要求是：
The structure of the desired output is as below:所需输出的结构如下：

Record Name : T 
Field Name :SeqNo   , Value :1 ( HardCoded ) 
Field Name : Name  , Value : Something(Hardcoded) 

Record Name: 
Group:
Child Record Name: A (This Child Record has max occurs 1 and Occurs only 1 per Company Name)
Req: For each company A record will be created only once 
Field Name: CompanyName , Value: From the input field Company Name 
Field Name: Segment , Value: A (HardCoded) 

Child Record Name : B ( This Child record Max occurs unbounded and groups all member under Each company Name ) 
Example and requirement : Input Member have company name “xyz” and total number of member having company name xyz is “3” so the B record will occur 3 times

Field Name: Company Name , Value: From the input field Company Name
Field Name: Person Name , Value : From the input field Person Name
Field Name: Country , Value : From the input field Country 
Field Name: State , value : From the input field State
Field Name : Amount , Value : from the input field Amount 

Child Record Name : C (This Child Record has max occurs 1 ) 

Field Name : Total Amount , Value : This will be the cumulative of the amounts under each company 
Example : If Company name XYZ have 3 member each of 1000 then the cumulative will be 3000

Child Record Name : K(This child Record has max occurs unbounded )
Field Name : State , Value : From the input field State
Field Name : TotAmount , Value : Below is the requirement

Requirement:要求：
The Field “CombinedState” in the input will tell whether is Yes or No , if its Yes then it create one record for each state and sum the amount for each state.输入中的字段“CombinedState”将判断是 Yes 还是 No ，如果是 Yes 则它为每个状态创建一个记录并总结每个状态的数量。

Example:例子：
For XYZ Company there are 3 members and their states are KS,AZ and KS , so we have to create two K record ie, one for KS and one for AZ , and we need to sum the amount for KS as XYZ have 2 member under KS state ,对于 XYZ 公司，有 3 个成员，他们的状态是 KS、AZ 和 KS，因此我们必须创建两个 K 记录，即一个用于 KS，一个用于 AZ，我们需要将 KS 的数量相加，因为 XYZ 下有 2 个成员KS 状态，

Problem:问题：
Each Record inside the group uses different keys , the XSLT what I have written is not working for the B and K records.组内的每个记录使用不同的键，我写的 XSLT 不适用于 B 和 K 记录。

I debugged your XSLT.我调试了你的 XSLT。
Your main mistake was to not feed the key from the outer xsl:for-each to the inner xsl:for-each .您的主要错误是没有将密钥从外部xsl:for-each给内部xsl:for-each 。 So changing如此变化

<xsl:for-each select="Detail/Member[generate-id(.)=generate-id(key('group2',concat(CompanyName,'|',PersonName)))]">

to到

<xsl:for-each select="key('group1',CompanyName)[generate-id(.)=generate-id(key('group2',concat(CompanyName,'|',PersonName)))]">

did the trick.成功了。 The same applies to the third xsl:for-each .这同样适用于第三个xsl:for-each 。

Here is the new XSLT:这是新的 XSLT：

</xsl:stylesheet>

The output doesn't exactly match your given desired XML, but I guess your version was erroneous, because the output of the above XSLT does fulfill your requirements.输出与您给定的所需 XML 不完全匹配，但我猜您的版本是错误的，因为上述 XSLT 的输出确实满足您的要求。
