Hello list,

I wish to transform an xml which has level information in each item (Table) to xml which has hierarchy as stated in those item's element.

<DataSet xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <Table>
       <Level>1</Level>
       <Description>Cars</Description>
   </Table>
   <Table>
       <Level>2</Level>
       <Description>BMW</Description>
   </Table>
   <Table>
       <Level>3</Level>
       <Description>316</Description>
   </Table>
   <Table>
       <Level>3</Level>
       <Description>Z4</Description>
   </Table>
   <Table>
       <Level>2</Level>
       <Description>Citroen</Description>
   </Table>
   <Table>
       <Level>3</Level>
       <Description>C2</Description>
   </Table>
   <Table>
       <Level>3</Level>
       <Description>C4 coupe</Description>
   </Table>
   <Table>
       <Level>2</Level>
       <Description>Alfa Romeo</Description>
   </Table>
   <Table>
       <Level>3</Level>
       <Description>156</Description>
   </Table>
   <Table>
       <Level>1</Level>
       <Description>Motorcycles</Description>
   </Table>
   ...
   ...
</DataSet>

Target xml should look something like this:

<NewDataSet>
   <Transport name="Cars">
      <Brand name="BMW">
         <Model>316</Model>
         <Model>Z4</Model>
      </Brand>
      <Brand name="Citroen">
         <Model>C2</Model>
         <Model>C4 coupe</Model>
      </Brand>
      <Brand name="Alfa Romeo">
         <Model>156</Model>
      </Brand>     </Transport>
   <Transport name="Motorcycle">
      ...
   </Transport>
</NewDataSet>
