I am trying to create a tree menu like parent & child categories in a hirearchy. but the question is the parent and nodes listed under different rows and the parent should be sorted according to the CatName1(order) and the child should also sort by ChildName(order) before displaying...some help please...

My sql  table is structured like this.

Product name     catName1List   CatName1(order)  childNameList    ChildName(order)
============================================================
434                  |        Cat1         |          0             |         Child1         |          0
344                  |        Cat1         |          1             |         Child1         |          2
432                  |        Cat2         |          1             |         Child2         |          0
435                  |        Cat2         |          0             |         Child2         |          1
433                  |        Cat3         |          2             |         Child3         |          1


As you can see from the above table structure, i have first parent node should be ordered by CatName1(order), and the child node should be ordered by  ChildName(order), also what exactly i want to achieve from this table is to get like this structure..

Cat 1
  |____ChildB
             |_434
  ____ChildA
             |_344            
 Cat 2
  |____ChildA
             |_432
   ____ChildE
             |_435          
Cat 3
  |____Child H
             |_433
             
and so on.
How would i query mySQL to get this result or php script? please help...and then i need to create xml file structure like this...

<Products>product lists</products>
<lists>
<catName1List>Cat1</catName1List>
<childNameList>ChildB </childNameList>
<Product name>434 </Product name>
<childNameList>ChildA</childNameList>
<Product name>344</Product name>
</lists>
<lists>
<catName1List>Cat2</catName1List>
<childNameList>ChildA </childNameList>
<Product name>432 </Product name>
<childNameList>ChildE</childNameList>
<Product name>435</Product name>
</lists>
<lists>
<catName1List>Cat3</catName1List>
<childNameList>ChildH </childNameList>
<Product name>433 </Product name>
</lists>
