使用 xslt，将名为“标准”的元素重命名为“产品”

Question

我必须转换以下xml输入，

<Standards xmlns="http://ws.wso2.org/dataservice">
        <Standard>

转换为以下输出格式。

在论坛中其他人的支持下，我能够编写以下 xslt 来完成此转换。

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:x="http://ws.wso2.org/dataservice"
    xmlns="http://ws.wso2.org/dataservice"
    exclude-result-prefixes="x"
    version="1.0">
    <xsl:output indent="yes" method="xml" />
    <!-- Identity Transform -->
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="x:Standard">
        <xsl:copy>
            <xsl:copy-of select="x:ProductID"/>
            <xsl:copy-of select="x:Prefix"/>
            <xsl:copy-of select="x:SNumber"/>
            <RelatedProducts>
                <xsl:apply-templates select=".//x:RelatedProduct"/>
            </RelatedProducts>
            <xsl:copy-of select="x:S1"/>
            <xsl:copy-of select="x:S2"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="x:RelatedProduct">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
            <RelationType><xsl:value-of select="name(..)"/></RelationType>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

但是现在我需要将所有当前命名为"标准"的元素重命名为"产品"，最终输出应如下所示。

我尝试了几种方法并更改了上面的xslt，但仍然没有运气。我是xslt的新手。我如何更改上面的 xslt 来完成这件事。任何帮助将不胜感激。

Answer 1

只需替换 中的<xsl:copy>

<xsl:template match="x:Standard">
                <xsl:copy>
                    <xsl:copy-of select="x:ProductID" />

与<Product>（当然还有结束标签）。就这么简单，无需修改其他内容，给

<xsl:template match="x:Standard">
                <Product>
                    <xsl:copy-of select="x:ProductID" />

结果是：

<?xml version="1.0"?>
<Standards xmlns="http://ws.wso2.org/dataservice">
    <Product>
        <ProductID>200057</ProductID>
        <Prefix>ISO</Prefix>
        <SNumber>1001</SNumber>
        <RelatedProducts>
            <RelatedProduct>
                <ProductID>1500163</ProductID>
                <RelationType>DraftProducts</RelationType>
            </RelatedProduct>
            <RelatedProduct>
                <ProductID>263973</ProductID>
                <Designation xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>
                <RelationType>ReferenceProducts</RelationType>
            </RelatedProduct>
            ...

如果您还想复制RelationId只需从最后一个模板中删除例外，使其如下所示：

<xsl:template match="x:RelatedProduct">
  <xsl:copy>
    <xsl:apply-templates select="@*|*"/>
    <RelationType><xsl:value-of select="name(..)"/></RelationType>
  </xsl:copy>
</xsl:template>

同时应用两者会给您确切的结果。
