Re: [xsl] Create xml file with recursive childnodes

[chun ji <cji_work@xxxxxxxxx>]

Hi Mukul, 
thank you for 2 solutions. But I see an issue for the
second one if the root obj has more that 1 child. 

For example, if the input xml is : 
"
<Objs>
  <obj name="a" child="b"/>
  <obj name="b" child="c"/>
  <obj name="b" child="d"/>
  <obj name="c" child="e"/>
  <obj name="b" child="f"/>
  <obj name="a" child="u"/>
</Objs>
"
, I get such results

" 
<?xml version="1.0" encoding="UTF-8"?>
<Obj name="a a">
   <Obj name="b">
      <Obj name="c">
         <Obj name="e"/>
      </Obj>
      <Obj name="d"/>
      <Obj name="f"/>
   </Obj>
</Obj>
".  


Regards,
