通过XSLT从块检索多个值在XML

Question

我有下面的XML：

<?xml version="1.0" encoding="UTF-8"?> 
<Report xmlns:fpml="http://www.fpml.org/FpML-5/confirmation" xmlns="http://www.eurexchange.com/EurexIRSFullInventoryReport" name="CB202 Full Inventory Report"> 
<reportNameGrp> 
    <CM> 
    <acctTypGrp name="A4"> 
    <ProductType name="Swap"> 
    <currTypCod value="EUR"> 
    </currTypCod> 
    <currTypCod value="GBP"> 
    </currTypCod> 
    </ProductType> 
    </acctTypGrp> 
    <acctTypGrp name="A8"> 
    <ProductType name="Swap"> 
    <currTypCod value="CHF"> 
    </currTypCod> 
    <currTypCod value="EUR"> 
    </currTypCod> 
    <currTypCod value="GBP"> 
    </currTypCod> 
    </ProductType> 
    </acctTypGrp> 
    </CM> 
</reportNameGrp> 
</Report> 

为此，我用这个XSLT转换（基于https://stackoverflow.com/a/27458587/2564301）：

<xsl:stylesheet version="1.0" 
    xmlns:fpml="http://www.fpml.org/FpML-5/confirmation" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:eur="http://www.eurexchange.com/EurexIRSFullInventoryReport"> 
    <xsl:output method="xml" version="1.0" encoding="UTF-8" 
     indent="yes" omit-xml-declaration="yes" /> 
    <xsl:template match="/eur:Report"> 
     <Eurexflows> 
      <xsl:apply-templates 
       select="eur:reportNameGrp/eur:CM/eur:acctTypGrp/eur:ProductType" /> 
     </Eurexflows> 
    </xsl:template> 
    <xsl:template match="eur:ProductType"> 
     <EurexMessageObject> 
      <name> 
       <xsl:value-of select="../@name" /> 
      </name> 
      <ProductType> 
       <xsl:value-of select="@name" /> 
      </ProductType> 
      <value> 
      <xsl:value-of select="eur:currTypCod/@value" /> 
      </value> 
     </EurexMessageObject> 
    </xsl:template> 
</xsl:stylesheet> 

现在我想我的输出XML如下：

<Eurexflows xmlns:eur="http://www.eurexchange.com/EurexIRSFullInventoryReport" 
    xmlns:fpml="http://www.fpml.org/FpML-5/confirmation"> 

    <EurexMessageObject> 
<name>A4</name> 
<ProductType>Swap</ProductType> 
<value>EUR,GBP</value> 
</EurexMessageObject> 
    <EurexMessageObject> 
     <name>A8</name> 
     <ProductType>Swap</ProductType> 
     <value>CHF,EUR,GBP</value> 
    </EurexMessageObject> 
</Eurexflows> 

我需要在我的XSLT中对进行哪些更改标签？

Answer 1

value-of不与多个匹配元素工作：

...在XSLT在someNodeSet（https://stackoverflow.com/a/6913772/2564301）

的 第一节点的只有1.0 <xsl:value-of select="someNodeSet"/>输出字符串值

<xsl:for-each>使用代替单个value-of：

<value> 
    <xsl:for-each select="eur:currTypCod/@value"> 
    <xsl:if test="position()&gt;1">,</xsl:if> 
    <xsl:value-of select="." /> 
    </xsl:for-each> 
</value>
