Question

我正在尝试从此XML中选择值并生成分组的XML输出。这是XML文件：我正在尝试使用name属性获取单个字段值：select =“field [@ name ='EmployeeEmployeeID']” ** 已编辑添加分数字段 **

我尝试使用以下XSL，但我似乎没有使用正确的选择器或正确的分组。任何帮助将不胜感激。

当前的xsl只输出没有标签的值而没有分组...

    1234
    John
    A
    Doe
    Title
    2017 Review
    Goal Title1A


    1234
    John
    A
    Doe
    Title
    2017 Review
    Goal Title2A


    1234
    John
    A
    Doe
    Title
    2018 Review
    Goal Title1B


    1234
    John
    A
    Doe
    Title
    2018 Review
    Goal Title2B

我从下面的建议开始，结果如下：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xpath-default-namespace="http://www.taleo.com/ws/integration/toolkit/2005/07">
  <xsl:output indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="/ExportXML">
    <Reviews>    
      <xsl:for-each-group select="record" 
        group-by="string-join((field[@name=('EmployeeEmployeeID','ReviewRequest')]),
        '|')">
        <ReviewRequest>
          <EEID>
            <xsl:value-of select="current-group()[1]/field[@name='EmployeeEmployeeID']"/>
          </EEID>
          <EEFirstName>
            <xsl:value-of select="current-group()[1]/field[@name='EmployeeFirstName']"/>
          </EEFirstName>
          <EEInitial>
            <xsl:value-of select="current-group()[1]/field[@name='EmployeeInitial']"/>
          </EEInitial>
          <EELastName>
            <xsl:value-of select="current-group()[1]/field[@name='EmployeeLastName']"/>
          </EELastName>
          <EETitle>
            <xsl:value-of select="current-group()[1]/field[@name='EmployeeTitle']"/>
          </EETitle>
          <ReviewRequest>
            <xsl:value-of select="current-group()[1]/field[@name='ReviewRequest']"/>
          </ReviewRequest>
            <Goals>
                <xsl:for-each select="current-group()/field[@name='Goal']">
                    <Goal>
                        <Goal><xsl:value-of select="."/></Goal>
                        <Score><xsl:value-of select="../field[@name='Score']"/></Score>
                    </Goal>
                </xsl:for-each>
            </Goals>
        </ReviewRequest>
      </xsl:for-each-group>      
    </Reviews>    
  </xsl:template>

</xsl:stylesheet>

产生这个结果：

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

   <ReviewRequest>
      <EEID>1234</EEID>
      <EEFirstName>John</EEFirstName>

Answer 1

您获得的输出是built-in template rules的结果。这是因为您没有考虑默认命名空间（http://www.taleo.com/ws/integration/toolkit/2005/07）。所以/ExportXML并不匹配任何内容。

除了考虑默认命名空间之外，还要考虑使用复合group-by而不是两个嵌套for-each-group＆＃39; s。

分组键是＆＃34; EmployeeEmployeeID＆＃34;的组合。字段和＆＃34; ReviewRequest＆＃34;领域。

假设除了目标之外的所有内容对于每个组都是相同的，您可以执行以下操作：

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xpath-default-namespace="http://www.taleo.com/ws/integration/toolkit/2005/07">
  <xsl:output indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="/ExportXML">
    <Reviews>
      <xsl:for-each-group select="record" 
        group-by="string-join((field[@name=('EmployeeEmployeeID','ReviewRequest')]),
        '|')">
        <ReviewRequest>
          <EEID>
            <xsl:value-of select="current-group()[1]/field[@name='EmployeeEmployeeID']"/>
          </EEID>
          <EEFirstName>
            <xsl:value-of select="current-group()[1]/field[@name='EmployeeFirstName']"/>
          </EEFirstName>
          <EEInitial>
            <xsl:value-of select="current-group()[1]/field[@name='EmployeeInitial']"/>
          </EEInitial>
          <EELastName>
            <xsl:value-of select="current-group()[1]/field[@name='EmployeeLastName']"/>
          </EELastName>
          <EETitle>
            <xsl:value-of select="current-group()[1]/field[@name='EmployeeTitle']"/>
          </EETitle>
          <ReviewRequest>
            <xsl:value-of select="current-group()[1]/field[@name='ReviewRequest']"/>
          </ReviewRequest>
          <xsl:for-each select="current-group()/field[@name='Goal']">
            <Goal><xsl:value-of select="."/></Goal>
          </xsl:for-each>
        </ReviewRequest>
      </xsl:for-each-group>      
    </Reviews>
  </xsl:template>

</xsl:stylesheet>

您还可以稍微简化元素创建（这也可以解释您添加的Score要求）...

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
  xpath-default-namespace="http://www.taleo.com/ws/integration/toolkit/2005/07">
  <xsl:output indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="/ExportXML">
    <Reviews>
      <xsl:for-each-group select="record" 
        group-by="string-join((field[@name=('EmployeeEmployeeID','ReviewRequest')]),
        '|')">
        <ReviewRequest>
          <xsl:apply-templates 
            select="current-group()[1]/field[not(@name=('Goal','Score'))]"/>
          <Goals>
            <xsl:apply-templates select="current-group()/field[@name='Goal']"/>
          </Goals>
        </ReviewRequest>
      </xsl:for-each-group>      
    </Reviews>
  </xsl:template>

  <xsl:template match="field[@name='Goal']">
    <Goal>
      <Goal><xsl:value-of select="."/></Goal>
      <xsl:apply-templates select="../field[@name='Score']"/>
    </Goal>
  </xsl:template>

  <xsl:template match="field">
    <xsl:element name="{replace(@name,'^(Employee)+(.*)','EE$2')}">
      <xsl:apply-templates/>
    </xsl:element>
  </xsl:template>

</xsl:stylesheet>

使用字段名称对XML记录进行分组使用XSL
