使用 xslt 從父節點重復元素到子節點

Question

我正在嘗試編寫一個 xsl 文件以方便將 xml 文件導入數據庫。 因此，我需要將父節點的 id 復制到子節點，以便它們在導入后用作外鍵。

輸入 XML 是：

為此，我編寫了以下代碼：

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

    <xsl:output indent="yes"/>  
    <xsl:strip-space elements="*"/>
    
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
    
    <xsl:template match="issuer | counterpart | invoiceHeader | paymentMethods/paymentMethodDetails | invoiceDetails | invoiceSummary">
        <issuer>
            <uid><xsl:value-of select="/RequestedDoc/invoicesDoc/invoice/uid"/></uid>
            <xsl:apply-templates/>
        </issuer>
    </xsl:template>
    
</xsl:stylesheet>

但它不起作用。 任何人都可以幫忙嗎？

缺少默認的命名空間處理。 我還簡化了您的第二個模板。

請嘗試以下 XSLT。

XSLT

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.aade.gr/myDATA/invoice/v1.0" xmlns:a="http://www.aade.gr/myDATA/invoice/v1.0" xmlns:icls="https://www.aade.gr/myDATA/incomeClassificaton/v1.0"
                xmlns:ecls="https://www.aade.gr/myDATA/expensesClassificaton/v1.0" exclude-result-prefixes="a">
    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>

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

    <xsl:template match="a:issuer | a:counterpart | a:invoiceHeader | a:paymentMethodDetails | a:invoiceDetails | a:invoiceSummary">
        <xsl:copy>
         <xsl:copy-of select="/a:RequestedDoc/a:invoicesDoc/a:invoice/a:uid"/>
         <xsl:apply-templates/>
      </xsl:copy>
    </xsl:template>
</xsl:stylesheet>
