Question

我正在尝试显示下面提到的xml的元素：

<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>

采用以下格式：

<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是我得不到正确的结果。

这是我的xslt：

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

是否有人对这个问题有所了解？

这个XSLT 1.0样式表：

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:msxsl="urn:schemas-microsoft-com:xslt"
 xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
 exclude-result-prefixes="msxsl">
    <xsl:param name="pNamespaceURI" select="'http://tempuri.org/'"/>
    <xsl:param name="pPrefix" select="'tem'"/>
    <xsl:variable name="vDummyRTF">
        <xsl:element name="{$pPrefix}:dummy" namespace="{$pNamespaceURI}"/>
    </xsl:variable>
    <xsl:variable name="vNamespaceNode"
     select="msxsl:node-set($vDummyRTF)/*/namespace::*[name()=$pPrefix]"/>
    <xsl:template match="root">
        <soapenv:Envelope>
            <xsl:copy-of select="$vNamespaceNode"/>
            <soapenv:Header>
                <xsl:copy-of select="$vNamespaceNode"/>
            </soapenv:Header>
            <soapenv:Body>
                <xsl:copy-of select="$vNamespaceNode"/>
                <xsl:apply-templates/>
            </soapenv:Body>
        </soapenv:Envelope>
    </xsl:template>
    <xsl:template match="*">
        <xsl:element name="{$pPrefix}:{name()}" namespace="{$pNamespaceURI}">
            <xsl:apply-templates/>
        </xsl:element>
    </xsl:template>
</xsl:stylesheet>

这个XSLT 2.0样式表：

<xsl:stylesheet version="2.0"

 xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <xsl:param name="pNamespaceURI" select="'http://tempuri.org/'"/>
    <xsl:param name="pPrefix" select="'tem'"/>
    <xsl:variable name="vNamespaceNode" as="node()">
        <xsl:namespace name="{$pPrefix}">
            <xsl:value-of select="$pNamespaceURI"/>
        </xsl:namespace>
    </xsl:variable>
    <xsl:template match="root">
        <soapenv:Envelope>
            <xsl:copy-of select="$vNamespaceNode"/>
            <soapenv:Header>
                <xsl:copy-of select="$vNamespaceNode"/>
            </soapenv:Header>
            <soapenv:Body>
                <xsl:copy-of select="$vNamespaceNode"/>
                <xsl:apply-templates/>
            </soapenv:Body>

    </xsl:template>
    <xsl:template match="*">

            <xsl:apply-templates/>
        </xsl:element>
    </xsl:template>
</xsl:stylesheet>

输出：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/">
    <soapenv:Header />
    <soapenv:Body>
        <tem:LogException>

        </tem:LogException>
    </soapenv:Body>

Answer 2

假设你只想深入两个级别，你可以试试这个：

<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中的最佳做法是尽可能避免使用<xsl:for-each>标记。您可以使用<xsl:apply-templates>

定义更具体的模板

循环遍历xsl中的元素但不能以期望的方式显示它
