这是我所理解的，但可能不是你想要的？

<!-- find the last of Element11 with any key -->
    <xsl:template match="Element11[not(following::Element11[key = current()/key])]">
       <result>
        <key><xsl:value-of select="key"/></key>
        <xsl:choose>
         <!-- are there more than one with this key? -->
         <xsl:when test="preceding-sibling::Element11[key = current()/key]">
           <!-- if yes it seems you want an Element wrapper -->
           <Element>
             <xsl:for-each select="preceding-sibling::Element11[key = current()/key]/number">
                <number><xsl:value-of select="."/></number>
             </xsl:for-each>
             <!-- the current one -->
             <number><xsl:value-of select="number"/></number>
           </Element>
         </xsl:when>
         <xsl:otherwise>
             <!-- only the current one -->
             <number><xsl:value-of select="number"/></number>
         </xsl:otherwise>
        </xsl:choose>
       </result>
     </xsl:template>

     <xsl:template match="Element11"/>

使用字符串的前三位数来循环并对输出中的元素进行分组
