我认识到这种变换的三个主要规则......但我无法想象变换的方式：

  1. 城市中具有“目的地ID”的所有元素将成为“CITY”类中的元素子元素。甚至是元素之间映射的连接。

  2. @name成为文本元素：只有“CITY”和“CITYLIST”再获得一层“<org><text><fill>@name</fill></text></org>”。其余元素可以直接放置：'<text>@name</text>'

  3. 如果元素中有另一个子元素，它将成为新元素。例如：对于“博物馆”，如果它具有元素“artmuseum”，则类名称变为“ARTMUSEUM”。而不是“博物馆”

    4. 问题是如何检查元素是否包含任何元素来调用相应的模板。因为这些子元素将成为新类，而不是其父元素。

此样式表：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:key name="ById" match="*" use="@id"/>
    <xsl:param name="pLowerCase" select="'qwertyuiopasdfghjklzxcvbnm'"/>

    <xsl:template match="country|citylist|city">
        <org id="{@id}"  class="{translate(name(),$pLowerCase,$pUpperCase)}">
            <xsl:apply-templates select="@name|citylist|city|destination"/>
        </org>
    </xsl:template>
    <xsl:template match="country/@name"/>
    <xsl:template match="citylist/@name|city/@name">
