你会看到XML不完全相同但标签总是在同一个地方,目前有1个重复867241

我不希望更改订单,只删除元素。

期望的输出将是;

<强>予。 XSLT 1.0解决方案:

以下是使用Muenchian分组的解决方案

<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:key name="kLineById" match="Line" use="ItemID|ITEMID"/>

 <xsl:template match="node()|@*">
     <xsl:copy>
       <xsl:apply-templates select="node()|@*"/>
     </xsl:copy>
 </xsl:template>

 <xsl:template match=
  "Line[not(generate-id() = generate-id(key('kLineById', ItemID|ITEMID)[1]))]"
  />
</xsl:stylesheet>

请注意

  1. Muenchian grouping 是XSLT 1.0中最有效的已知通用分组方法。

  2. 使用纯 "push" style


  3. <强> II。 XSLT 2.0解决方案:

    <xsl:stylesheet version="2.0"
        xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
        <xsl:output omit-xml-declaration="yes" indent="yes"/>
    
     <xsl:template match="/*">
         <XML>
           <xsl:for-each-group select="Line" group-by="ItemID | ITEMID">
             <xsl:sequence select="."/>
           </xsl:for-each-group>
         </XML>
     </xsl:template>
    </xsl:stylesheet>

答案 1 :(得分:2)

以下转型对我有用:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="Line">
        <xsl:copy-of select="." />
    </xsl:template>
    <xsl:template match="/XML">
    <XML>
    <xsl:apply-templates select="Line[not(
        ItemID=preceding-sibling::Line/ItemID or
        ItemID=preceding-sibling::Line/ITEMID or
        ITEMID=preceding-sibling::Line/ItemID or
        ITEMID=preceding-sibling::Line/ITEMID)]" />
    </XML>
</xsl:template>
</xsl:transform>

如果ItemID / ITEMID拼写为一致的大写或骆驼案,则表达式可以简化。
