[jdom-interest] Transforming flat xml to hierachial xml format

[Philip Nelson]

I can't say I understand at all how you got the second document from the first,
but assuming that there is logical ways of grouping folder and leaf by
managerId, this looks like a better job for XSLT.  While you could use xpath to
get those relationships in either jdom or xslt, I think xslt is a better choice
when the documents have little in common.

> I have an xml file that has 100 "Employee" elements. The elements are

> <Employees>
>   <employee id="1" name="emp1" managerId="2" />
>   <employee id="2" name="emp2" managerId="5" />
>   <employee id="3" name="emp3" managerId="5" />
>   <employee id="4" name="emp4" managerId="2" />
>   <employee id="5" name="emp5" />
> </Employees>
> 
> I have the above tree as a JDOM document. Here is how I want to transform it

> <Employees>
>           <folder  id="5" name="emp5" >
>                          <folder  id="2" name="emp2">
>                                  <leaf  id="4" name="emp4" />
>                                  <leaf  id="1" name="emp1" />
>                         </folder>
>                         <leaf  id="3" name="emp3" />
>        </folder>
> </Employees>
