可我們能寫一個xsl做到這一點？

感謝

你能定義複製？也許更簡潔的樣本會更好。 – 2009-06-20 23:37:11

試試這個：

<?xml version="1.0" encoding="utf-8"?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 

    <xsl:template match="/"> 
    <xsl:apply-templates select="RESPONSE"/> 
    </xsl:template> 

    <xsl:template match="RESPONSE"> 
    <RESPONSE> 
     <xsl:apply-templates select="RECORD"/> 
    </RESPONSE> 
    </xsl:template> 

    <xsl:template match="RECORD"> 
    <xsl:variable name="this" select="."/> 
    <xsl:variable name="country" select="COUNTRY_ID/text()"/> 
    <xsl:if test="not(../RECORD[COUNTRY_ID/text() = $country and generate-id($this) != generate-id(.)])"> 
     <xsl:copy-of select="."/> 
    </xsl:if> 
    </xsl:template> 

</xsl:stylesheet>

這一切都是假設，當你說「重複」你的意思是COUNTRY_ID具有相同的內容。我的XSLT似乎會生成您想要的輸出。

謝謝你這正是我想要的。 – user114086 2009-06-21 02:09:03

這個選擇會給你一個有重複的COUNTRY_ID的集合。 （> 1）

select="/RESPONSE/RECORD/COUNTRY_ID/*[count(.|key('x',name())[1])>1]">

使用該設置，然後從您的選擇中排除這些。

我沒有運行測試，但它應該給你設置工作。
