上一个问题

再次在输入 xml 中进行小更新，其他验证都相同.这里只有章节(元素)在改变，而不是章节 i 会有数字

Again Small Update in input xml the other validation are all same. Here only the chapter (element) is changing instead of chapter i will have numbers

<tutorial>
<lessons>
    <lesson>
     12000 Bat 20 
    </lesson>
    <lesson>
        15000 Pen Ball 10~ 
    </lesson>
    <lesson>
        14000 Book 
    </lesson>
    <lesson>
        note lesson
    </lesson>
</lessons>
<lessons1>
    <lesson>
        24000 Pencil 10
    </lesson>
    <lesson>
        description page
    </lesson>
    <lesson>
        8000 Car Tank 25
    </lesson>
</lessons1>

在上一个问题中，我们有章节是第一个节点(第 20 章)，但这里我有 12000 个 bat 20

In the previous question we have Chapter was the first node (chapter Bat 20) but here I have 12000 bat 20

上述输入的期望输出是

<Geography>
<historical>
  <social>
     <toc1>
        <toc>
           <chapter>12000</chapter>

@Dimitre &@Tomalak 从下一次我会写出准备充分的问题，我肯定会把它和我所拥有的解决方案一起发布，现在我开始用下面的输出和以前的输出更快地学习(XSLT).

@Dimitre & @Tomalak From next time i will write fully prepared question and definitely i will post it with the solution what i have, now i am started learning little faster(XSLT) with this below output and previous output.

请在这里指导我

应用于提供的 XML 文档时:

         12000 Bat 20
        </lesson>
        <lesson>
            15000 Pen Ball 10~
        </lesson>
        <lesson>
            14000 Book
        </lesson>
        <lesson>
            note lesson
        </lesson>
    </lessons>
    <lessons1>
        <lesson>

        <lesson>
            description page

        <lesson>
            8000 Car Tank 25
        </lesson>
    </lessons1>
</tutorial>

产生想要的、正确的结果:
