提前感谢您的帮助 我有一个大的xml文件，需要合并/求和行。我花了很多时间在我的XSLT For Dummies书上并尝试了许多论坛解决方案的变化，但我甚至都没有接近。我们非常感谢您提供的任何指导。

使用 Muenchian方法

XSLT 1.0：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="text" indent="yes"/>

  <xsl:key name="k" match="Report_Entry" use="concat(emp, '|', pay)"/>

  <xsl:template match="/">
    <xsl:apply-templates 
      select="//Report_Entry[generate-id() = generate-id(key('k', concat(emp, '|', pay)))]"/>
  </xsl:template>

  <xsl:template match="Report_Entry">
    <xsl:value-of 
      select="concat(union, '        ', fac, ' ', job, ' ', pay, ' ',
        sum(key('k', concat(emp, '|', pay))/hours))"/>
    <xsl:text>
</xsl:text>
  </xsl:template>

</xsl:stylesheet>

完全符合XSLT精神的简短转型（推送风格）：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="text"/>
 <xsl:variable name="vT" select="'&#9;'"/>

 <xsl:key name="kEntryByempPay" match="Report_Entry" use="concat(emp,'|',pay)"/>

  <xsl:template match=
  "/*/*[generate-id()=generate-id(key('kEntryByempPay', concat(emp,'|',pay))[1])]">
    <xsl:value-of select="concat(union, $vT, fac, $vT, job, $vT, pay, $vT,
                                 sum(key('kEntryByempPay', concat(emp,'|',pay))/hours),
                                 '&#xA;')"/>
