XSLT -创建新的元素和值

Question

这是原始的输入文件。

<?xml version="1.0" encoding="UTF-8" ?>
<SSC>
    <Payload>
        <Item>
            <Characteristics>
                <CharacteristicCode>NRF COLOR</CharacteristicCode>
                <AlphaValues>
                    <CharacteristicCode>NRF COLOR</CharacteristicCode>
                    <DiscreteValueAlphanumeric>000</DiscreteValueAlphanumeric>
                </AlphaValues>
            </Characteristics>
            <Characteristics>
                <CharacteristicCode>SIZE</CharacteristicCode>
                <AlphaValues>
                    <CharacteristicCode>SIZE</CharacteristicCode>
                    <DiscreteValueAlphanumeric>10</DiscreteValueAlphanumeric>
                </AlphaValues>
                <AlphaValues>
                    <CharacteristicCode>SIZE</CharacteristicCode>
                    <DiscreteValueAlphanumeric>11</DiscreteValueAlphanumeric>
                </AlphaValues>
                <AlphaValues>
                    <CharacteristicCode>SIZE</CharacteristicCode>
                    <DiscreteValueAlphanumeric>12</DiscreteValueAlphanumeric>
                </AlphaValues>
            </Characteristics>
            <Characteristics>
                <CharacteristicCode>UPC</CharacteristicCode>
                <AlphaValues>
                    <CharacteristicCode>UPC</CharacteristicCode>
                    <DiscreteValueAlphanumeric></DiscreteValueAlphanumeric>
                </AlphaValues>
            </Characteristics>
        </Item>
    </Payload>
</SSC>

基于特征代码“大小”，我需要附加一个名为"UPC“的特征元素。对于每个大小，将创建一个UPC代码。所以最终结果会是这样

<Characteristics>
    <CharacteristicCode>UPC</CharacteristicCode>
    <AlphaValues>
        <CharacteristicCode>UPC</CharacteristicCode>
        <DiscreteValueAlphanumeric>UPC-10</DiscreteValueAlphanumeric>
    </AlphaValues>
    <AlphaValues>
        <CharacteristicCode>UPC</CharacteristicCode>
        <DiscreteValueAlphanumeric>UPC-11</DiscreteValueAlphanumeric>
    </AlphaValues>
    <AlphaValues>
        <CharacteristicCode>UPC</CharacteristicCode>
        <DiscreteValueAlphanumeric>UPC-12</DiscreteValueAlphanumeric>
    </AlphaValues>
</Characteristics>

到目前为止，这是我的密码。由于循环的问题，我无法在字段中连接'UPC‘。

    <xsl:template match="/SSC/Payload/Item/Characteristics/AlphaValues[CharacteristicCode='UPC']">
        <xsl:for-each select = "/SSC/Payload/Item/Characteristics/AlphaValues[CharacteristicCode='SIZE']/DiscreteValueAlphanumeric">
            <AlphaValues>
                <CharacteristicCode>UPC</CharacteristicCode>
                <DiscreteValueAlphanumeric>
                    <xsl:value-of select = "/SSC/Payload/Item/Characteristics/AlphaValues[CharacteristicCode='SIZE']/DiscreteValueAlphanumeric"/>
                </DiscreteValueAlphanumeric>
            </AlphaValues>
        </xsl:for-each>
    </xsl:template>

但这就是我最后的下场。在每个循环中，所有的值都连接在一起。

<?xml version="1.0" encoding="UTF-8"?>
<SSC>
   <Payload>
      <Item>
         <Characteristics>
            <CharacteristicCode>NRF COLOR</CharacteristicCode>
            <AlphaValues>
               <CharacteristicCode>NRF COLOR</CharacteristicCode>
               <DiscreteValueAlphanumeric>000</DiscreteValueAlphanumeric>
            </AlphaValues>
         </Characteristics>
         <Characteristics>
            <CharacteristicCode>SIZE</CharacteristicCode>
            <AlphaValues>
               <CharacteristicCode>SIZE</CharacteristicCode>
               <DiscreteValueAlphanumeric>10</DiscreteValueAlphanumeric>
            </AlphaValues>
            <AlphaValues>
               <CharacteristicCode>SIZE</CharacteristicCode>
               <DiscreteValueAlphanumeric>11</DiscreteValueAlphanumeric>
            </AlphaValues>
            <AlphaValues>
               <CharacteristicCode>SIZE</CharacteristicCode>
               <DiscreteValueAlphanumeric>12</DiscreteValueAlphanumeric>
            </AlphaValues>
         </Characteristics>
         <Characteristics>
            <CharacteristicCode>UPC</CharacteristicCode>
            <AlphaValues>
               <CharacteristicCode>UPC</CharacteristicCode>
               <DiscreteValueAlphanumeric>10 11 12</DiscreteValueAlphanumeric>
            </AlphaValues>
            <AlphaValues>
               <CharacteristicCode>UPC</CharacteristicCode>
               <DiscreteValueAlphanumeric>10 11 12</DiscreteValueAlphanumeric>
            </AlphaValues>
            <AlphaValues>
               <CharacteristicCode>UPC</CharacteristicCode>
               <DiscreteValueAlphanumeric>10 11 12</DiscreteValueAlphanumeric>
            </AlphaValues>
         </Characteristics>
      </Item>
   </Payload>
</SSC>

对不起，我之前试图简化我的问题，但没有意识到它正在造成更多的问题。真的很感谢你的建议！

这样试试？

XSLT1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:template match="/SSC">
    <Characteristics>
        <CharacteristicCode>UPC</CharacteristicCode>
        <xsl:for-each select="Payload/Item/Characteristics[CharacteristicCode='SIZE']/AlphaValues">
            <AlphaValues>
                <CharacteristicCode>UPC</CharacteristicCode>
                <DiscreteValueAlphanumeric>
                    <xsl:text>UPC-</xsl:text>
                    <xsl:value-of select="DiscreteValueAlphanumeric"/>
                </DiscreteValueAlphanumeric>
            </AlphaValues>
        </xsl:for-each>
   </Characteristics>
</xsl:template>

</xsl:stylesheet>

注意xsl:for-each内部使用的相对路径。
