Question

我想将parentnode元素的值复制到子节点，如下所示。有人可以为我指出正确的方向吗？谢谢！

这是xml文件。

<mainpart id="295928" num="1-MS15" quantity="1">
    <explicitQuantity>1</explicitQuantity>

            </part>
        </singlepart>
    </proxy>
</mainpart>

这是我的xsl，我知道这是错误的，但是我不知道如何解决它。

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <xsl:output method="xml" encoding="UTF-8" indent="yes"/>

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

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

    <xsl:template match="part">     
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" />
            <UserAttribute10>"$mainpartmark"</UserAttribute10>  
        </xsl:copy>     
    </xsl:template>
</xsl:stylesheet>

这是我想要的结果，我想在Part节点的每一端添加节点UserAttr10，其值来自mainpart节点。

    <explicitQuantity>1</explicitQuantity>

Answer 1

由于只有一个mainpart节点（根元素），因此只需将变量声明为全局变量（xsl:stylesheet的子代）

<xsl:variable name="mainpartmark" select="/mainpart/@num" />

（在这种情况下，您不需要匹配mainpart的模板）。

然后，要使用它，只需执行此操作...

<UserAttribute10>
   <xsl:value-of select="/mainpart/@num" />
</UserAttribute10>

尝试使用此XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    exclude-result-prefixes="xsi">

    <xsl:output method="xml" encoding="UTF-8" indent="yes"/>

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

    <xsl:variable name="mainpartmark" select="/mainpart/@num" />

    <xsl:template match="part">     
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" />
            <UserAttribute10>
                <xsl:value-of select="$mainpartmark" />
            </UserAttribute10>  
        </xsl:copy>     
    </xsl:template>
</xsl:stylesheet>

当然，您也可以完全不使用变量，而只需执行<xsl:value-of select="/mainpart/@num" />。

而且，如果有多个mainpart节点（在单个根元素下），则也可以执行<xsl:value-of select="ancestor::mainpart/@num" />

将父节点值复制到子节点
