获取要为每个父节点显示的子节点

标签： xslt

我知道这可能听起来像是一个常见的问题，但我在这个网站上尝试了所有类似的解决方案并没有成功。现在我正在尝试使用xslt将现有的xml文档转换为符合新架构的xml文档。我正在尝试为每个产品显示名称和partnum。但是我只得到一个包含所有名称和partnums的产品节点。我尝试过为每个循环使用一个，我尝试过这个解决方案how to get a transformed xml file with all child tags of every occurance of parent tag under only one parent tag的结果非常接近，但唯一的问题是我将所有产品终止标签嵌套在产品标签中。

这是我当前的xml：

我不确定你为什么要在那里进行身份转换，因为你只想要一个非常有限的特定子集。但是，这应该可以解决问题：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:template match="/CATALOG">
     <xsl:copy>
       <xsl:apply-templates />
     </xsl:copy>
    </xsl:template>

    <xsl:template match="PRODUCT">
     <xsl:copy>
        <NAME><xsl:value-of select="@NAME"/></NAME>
        <PARTNUM><xsl:value-of select="@PARTNUM"/></PARTNUM>
     </xsl:copy>
    </xsl:template>

</xsl:stylesheet>
