【问题描述】：

是否有使用 XSL 或 java.text.MessageFormat 实现以下目标的通用方法？

【参考方案1】：

如果您输入的 XML 如下：

<Order OrderNo="T122345">
<Customer FirstName="John" LastName="Doe" MobileNo="123456789"/>
<OrderDates>
    <OrderDate Type="PickDate" Name="PickUpdateDate" Value="2017-11-10 10:00:00" />
</OrderDates>
</Order>

然后使用 XSL 如下：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml"/>    
    <!--prepare message formatted template as below-->
    <xsl:template name="message">
        <xsl:param name="client.firstname"/>
        <xsl:param name="client.lastname"/>
        <xsl:param name="client.order.no"/>
        <xsl:param name="client.pickup.date"/>
        <xsl:param name="client.mobile.no"/>
        <xsl:variable name="var.h" select="concat('&#xa;', 'hi ', $client.firstname, ' ', $client.lastname, ',', '&#xa;', '', '&#xa;')"/>
        <xsl:variable name="var.b.str1" select="concat('Thanks for your order # is ', $client.order.no, '.', '&#xa;')"/>
        <xsl:variable name="var.b.str2" select="concat('We will send you updates on pick up by ', $client.pickup.date, ' on your mobile # ', $client.mobile.no, '.', '&#xa;')"/>
        <xsl:variable name="var.s" select="concat('', '&#xa;', 'Regards', '&#xa;', 'Team', '&#xa;')"/>           
        <Message>       
            <xsl:value-of select="concat($var.h, $var.b.str1, $var.b.str2, $var.s)"/>    
        </Message>        
    </xsl:template>
    <!--run you formatted message template by call-template function-->
    <xsl:template match="/Order">
        <xsl:call-template name="message">
            <xsl:with-param name="client.firstname" select="./Customer/@FirstName" />
            <xsl:with-param name="client.lastname" select="./Customer/@LastName" />
            <xsl:with-param name="client.order.no" select="./@OrderNo" />
            <xsl:with-param name="client.pickup.date" select="./OrderDates/OrderDate[@Type = 'PickDate' and @Name = 'PickUpdateDate']/@Value" />
            <!--below you can pass city code as below for mobile no-->
            <xsl:with-param name="client.mobile.no" select="concat('91-', ./Customer/@MobileNo)" />
        </xsl:call-template>
    </xsl:template>
</xsl:stylesheet>

你会达到预期的效果：

<?xml version="1.0" encoding="UTF-8"?>
<Message>
hi John Doe,

Thanks for your order # is T122345.
We will send you updates on pick up by 2017-11-10 10:00:00 on your mobile # [phone].
