XSLT - 更新标题 [英] XSLT - Updating the Header

问题描述

下面给出了我的请求 XML，还给出了我使用的 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

The request XML i have is given below and the XSLT transformation Iam using is also given. Unfortunately the ordertotal xml tag is repeating twice after transformation. How can i update the existing tag rather than inserting double tag

推荐答案

因为您的源 XML 中已经存在一个 ordertotal 元素，而不是匹配结果并创建新的 ordertotal 元素，只需使用以下内容匹配 ordertotal 元素模板.

Because you already have present an ordertotal element in your source XML, instead of matching result and creating the new ordertotal element, just match the ordertotal element by using the following template.

<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>
