XML的分組節點XSLT 1.0

Question

輸入：

輸入XML

<Root> 
    <Number>1</Number> 
    <Reference>100</Reference> 

    <Number>2</Number> 
    <Reference>101</Reference> 

    <Number>3</Number> 
    <Reference>100</Reference> 

    <Number>4</Number> 
    <Reference>102</Reference> 

    <Number>5</Number> 
    <Reference>100</Reference> 
</Root> 

預期輸出：

<Root> 
    <Number>1</Number> 
    <Reference>100</Reference> 
    <RefNumber>1</RefNumber> 

    <Number>2</Number> 
    <Reference>101</Reference> 
    <RefNumber>1</RefNumber> 

    <Number>3</Number> 
    <Reference>100</Reference> 
    <RefNumber>2</RefNumber> 

    <Number>4</Number> 
    <Reference>102</Reference> 
    <RefNumber>1</RefNumber> 

    <Number>5</Number> 
    <Reference>100</Reference> 
    <RefNumber>3</RefNumber> 
</Root> 

如何分組基於根/參考做，並添加序列號，RefNumber在xslt 1.0中輸出？

由於提前做這個

Answer 1

的方法之一是使用XSL ：數。每當你匹配參考元素，複製元素，並與參考元素具有相同值的數量增加RefNumber元素：

<xsl:template match="Reference"> 
    <xsl:copy-of select="." /> 
    <xsl:variable name="Ref" select="." /> 
    <RefNumber><xsl:number count="Reference[. = $Ref]" /></RefNumber> 
</xsl:template> 

以下是完整的XSLT

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

    <xsl:template match="Reference"> 
     <xsl:copy-of select="." /> 
     <xsl:variable name="Ref" select="." /> 
     <RefNumber><xsl:number count="Reference[. = $Ref]" /></RefNumber> 
    </xsl:template> 

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

當應用於您的示例XML時，將輸出以下內容：

<Root> 
    <Number>1</Number> 
    <Reference>100</Reference> 
    <RefNumber>1</RefNumber> 

    <Number>2</Number> 
    <Reference>101</Reference> 
    <RefNumber>1</RefNumber> 

    <Number>3</Number> 
    <Reference>100</Reference> 
    <RefNumber>2</RefNumber> 

    <Number>4</Number> 
    <Reference>102</Reference> 
    <RefNumber>1</RefNumber> 

    <Number>5</Number> 
    <Reference>100</Reference> 
    <RefNumber>3</RefNumber> 
</Root> 

請注意使用身份轉換模板來複制其他現有節點。
