下面给出了我的请求 XML，并且还给出了我正在使用的 XSLT 转换。不幸的是，ordertotal xml 标记在转换后重复了两次。如何更新现有标签而不是插入双标签

请求 XML 是

XSLT 是

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
   <xsl:output method="xml" indent="yes"/>
 <xsl:template match="@*|node()">
      <xsl:copy>
         <xsl:apply-templates select="@*|node()"/>
      </xsl:copy>
   </xsl:template>

 <xsl:template match="return">
        <xsl:copy>
            <xsl:copy-of select="@*|*" />
<ordertotal>
                <xsl:value-of select="sum(orderDetails/(itemPrice*itemQty))" />
            </ordertotal>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

响应 XML 显示重复标记是

因为您已经在源 XML 中显示了 ordertotal 元素，所以无需匹配结果并创建新的 ordertotal 元素，只需使用以下模板匹配 ordertotal 元素。

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:output method="xml" indent="yes"/>

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

     <xsl:template match="ordertotal">
         <xsl:copy>
            <xsl:value-of select="sum(../orderDetails/(itemPrice*itemQty))" />
         </xsl:copy>
    </xsl:template>

</xsl:stylesheet>
