这是由1 xslt生成的xml。我基本上想要检查位置选项卡下的2条记录是否相似，然后只保留1个其他记录。在这种情况下，输出应如下所示。

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

    <Employee>

Answer 1

要删除重复记录，您可以使用Muenchian分组：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="no" indent="yes"/>
<xsl:strip-space elements="*"/>
  <xsl:key name="seqNumByRecord" match="Record" use="SeqNum"/>
  <xsl:template match="node()|@*">
    <xsl:copy>
        <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>
  <xsl:template match=
  "Record[not(generate-id() = generate-id(key('seqNumByRecord', SeqNum)[1]))]"
  />
</xsl:stylesheet>

第一个模板是identity transform，它匹配所有属性和节点并复制它们。第二个模板是一个匹配所有重复项的空模板。由于模板为空，因此将删除这些记录。有关Muenchian Grouping的详细解释，建议使用Jeni Tennison的这篇文章：http://www.jenitennison.com/xslt/grouping/muenchian.html，您还可以在Stackoverflow上找到许多优秀的答案。

对于多样性，第二种解决方案：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output omit-xml-declaration="yes" indent="yes"/>
  <xsl:strip-space elements="*"/>
  <xsl:template match="node()|@*">
    <xsl:copy>
       <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="Record[SeqNum = following::Record/SeqNum]"/>
</xsl:stylesheet>

在此方法中，用于删除重复项的空模板会匹配与以下记录具有相同SeqNum的所有记录。正如您在上述文章中所发现的那样，Muenchian方法被认为更有效。
