String 如何使用xsl连接带有两个不同分隔符的字符串

string xslt

String 如何使用xsl连接带有两个不同分隔符的字符串,string,xslt,concatenation,delimiter,String,Xslt,Concatenation,Delimiter,我有一个XML <main> <DATA_RECORD> <COMPONENT_SID>100</COMPONENT_SID> <GROUP_ID>1</GROUP_ID> </DATA_RECORD> <DATA_RECORD> <COMPONENT_SID>200</COMPONENT_SID> <GROUP_ID>1

我有一个XML

<main>
  <DATA_RECORD>
    <COMPONENT_SID>100</COMPONENT_SID>
    <GROUP_ID>1</GROUP_ID>

我想使用xsl解析成另一个XML。输出将是

<comp value="100,200,400|10,20|2,4,8,16"/>

其中属于不同组id的组件_SID用“|”分隔。属于同一组id的组件_SID应与“，”连接。我使用了以下xsl

<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
          <xsl:element name="comp">
             <xsl:attribute name="value">
                 <xsl:call-template name="join"> 
                        <xsl:with-param name="list" select="//DATA_RECORD[GROUP_ID=1]/COMPONENT_SID" /> 
                        <xsl:with-param name="separator" select="','" />                                             
                  </xsl:call-template> 
              </xsl:attribute>
        </xsl:element>
  </xsl:template>

   <xsl:template name="join"> 
    <xsl:param name="list" /> 
    <xsl:param name="separator"/>     
    <xsl:for-each select="$list"> 
      <xsl:value-of select="." /> 
      <xsl:if test="position() != last()"> 
        <xsl:value-of select="$separator" />         
      </xsl:if> 
    </xsl:for-each> 
  </xsl:template> 
</xsl:stylesheet>

结果是

<comp value="100,200,400"/>

但我不知道如何用“|”分隔其他组件组。有人能帮我吗

提前感谢

使用

current-group（）

在每个项目（或组）前面使用相同的简单逻辑，而不是第一个，并使用相应的分隔符

使用

current-group（）

在每个项目（或组）前面使用相同的简单逻辑，而不是第一个，并使用相应的分隔符

XSLT 2.0解决方案可以进一步缩短为：

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>

<xsl:template match="/">
  <xsl:variable name="vResult">
   <xsl:for-each-group select="*/*" group-by="GROUP_ID">
    <xsl:if test="not(position()=1)">|</xsl:if>
    <xsl:value-of select="current-group()/COMPONENT_SID" separator=","/>
   </xsl:for-each-group>
  </xsl:variable>

  <comp value="{$vResult}"/>
