【问题描述】：
上一篇文章 - Add attribute based on Node name (incremental) in xsl
感谢 Martin，我正在完成一个基于相同代码的后续项目。在这个项目中，我需要能够增加父节点以在原始的基础上创建一个有点关系的 xml 输出。我还需要为与当前节点相关的属性创建关系。
期望结果的总结
- 将所有节点列为 - 已完成
- a) 将所有父节点列为子关系的 ID 字段 - 完成
- b) 将所有子节点（没有子节点的最低级别节点）列为 - 已完成
- c) 列出所有属性：
- i) 如果不存在子节点 - 无法 为父节点拉###
- ii) 如果子节点存在 - 无法为父节点拉###
输入xml：
<xml>
<individual attr="test" attr2="test3" attr3="test2">
<name>
<firstname seq="1">Me</firstname>
<lastname>Last</lastname>
</name>
<addresses>
<address>
<street>1234 Main</street>
<city>Anytown</city>
<state>TX</state>
</address>
<address>
<street>4321 Central Ave</street>
<city>Bixby</city>
<state>ND</state>
</address>
</addresses>
<employeers>
<employeer>
<name>
<firstname seq3="99">Employer1</firstname>
<lastname>EmployerLast</lastname>
</name>
<addresses>
<address>
<street>1234 Employer1</street>
<city>Smallville</city>
<state>CT</state>

<employeer attr="test" attr2="test3" attr3="test2">
