如何将来自<xsl：value-of =“” select =“ @”>的字段放入标记内？

Question

我不能在标签内添加带有（<xsl:value-of select=）的字段

我正在创建一个XSLT模板，该模板将数据从Excel转换为XML。一切正常，但现在我想将excel用户名（@User_Name）添加到userdata标签。

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">
<xsl:template match="/">
    <tXML>
        <Header>
            <Source>TESTE</Source>
            <Action_Type>Upgrade</Action_Type>
            <Message_Type>User</Message_Type>
            <Company_ID>200000002</Company_ID>

            <Internal_Date_Time_Stamp>08/09/2017 17:35:00</Internal_Date_Time_Stamp>
        </Header>
        <Message>               
            <xsl:for-each select="//rs:data">
                <xsl:apply-templates/>
            </xsl:for-each>
        </Message>
    </tXML>

<xsl:template match="//z:row">

            <Location_Name>
                <xsl:value-of select="@Location_Name"/>
            </Location_Name>
            <Role_Name>
                <xsl:value-of select="@Role_Name"/>

            <Last_Name>
                <xsl:value-of select="@Last_Name"/>
            </Last_Name>
