循环遍历 xsl 中的元素但无法以所需的方式显示它

Question

我试图显示下面提到的 xml 元素：

<root>
  <LogException>
     <exceptionNotificationGroup>Person</exceptionNotificationGroup>
     <exceptionType>Implimentation Test</exceptionType>
     <createdDatetime>2011-03-29</createdDatetime>
     <exceptionSource>INFINITY</exceptionSource>
     <exceptionSourceReferenceId>2345610</exceptionSourceReferenceId>
     <exceptionTarget>RMB</exceptionTarget>
     <sourceSystem>ODS</sourceSystem>
     <message>Mandatory Field Missing-Test</message>
  </LogException>
  <LogException>
     <exceptionNotificationGroup>Vinayak</exceptionNotificationGroup>
     <exceptionType>Implimentation Testing</exceptionType>
     <createdDatetime>2012-03-29</createdDatetime>
     <exceptionSource>INFINITY Check</exceptionSource>
     <exceptionSourceReferenceId>2345610</exceptionSourceReferenceId>
     <exceptionTarget>ORMB</exceptionTarget>
     <sourceSystem>ODS</sourceSystem>
     <message>Mandatory Field Missing-Test</message>
  </LogException>
</root>

采用下面给出的格式：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
              xmlns:tem="http://tempuri.org/">
  <soapenv:Header/>
  <soapenv:Body>
  <tem:LogException>
     <tem:exceptionNotificationGroup>Person</tem:exceptionNotificationGroup>
     <tem:exceptionType>Implimentation Test</tem:exceptionType>
     <tem:createdDatetime>2011-03-29</tem:createdDatetime>
     <tem:exceptionSource>INFINITY</tem:exceptionSource>
     <tem:exceptionSourceReferenceId>2345610</tem:exceptionSourceReferenceId>
     <tem:exceptionTarget>RMB</tem:exceptionTarget>
     <tem:sourceSystem>ODS</tem:sourceSystem>
     <tem:message>Mandatory Field Missing-Test</tem:message>
      </tem:LogException>
     <tem:LogException>
      <tem:exceptionNotificationGroup>Vinayak</tem:exceptionNotificationGroup>
     <tem:exceptionType>Implimentation Testing</tem:exceptionType>
     <tem:createdDatetime>2012-03-29</tem:createdDatetime>
     <tem:exceptionSource>INFINITY Check</tem:exceptionSource>
     <tem:exceptionSourceReferenceId>2345610</tem:exceptionSourceReferenceId>
     <tem:exceptionTarget>ORMB</tem:exceptionTarget>
     <tem:sourceSystem>ODS</tem:sourceSystem>
     <tem:message>Mandatory Field Missing-Test</tem:message>
   </tem:LogException>
  </soapenv:Body>
</soapenv:Envelope>

通过使用 xslt，我尝试了很多使用不同类型的循环，但没有得到正确的结果。

这是我的 xslt：

<?xml version="1.0" encoding="UTF-8" ?>

有人对这个问题有答案吗？

此 XSLT 1.0 样式表：

Answer 2

假设您只想深入两层，您可以尝试以下操作：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
    <xsl:output omit-xml-declaration="yes" indent="yes"/>

    <xsl:template match="/root">
        <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
            <soapenv:Header/>
            <soapenv:Body>
                <xsl:apply-templates select="*"/>
            </soapenv:Body>
        </soapenv:Envelope>
    </xsl:template>

    <xsl:template match="root/*">
        <xsl:element name="tem:{name()}">
            <xsl:apply-templates select="*"/>
        </xsl:element>
    </xsl:template>

    <xsl:template match="root/*/*">
        <xsl:element name="tem:{name()}">
            <xsl:value-of select="."/>
        </xsl:element>
    </xsl:template>

</xsl:stylesheet>

通常，XSLT 中的最佳实践是尽可能避免使用 标记。您可以定义更具体的模板，并使用 调用这些模板
