How to generate Xpath for a node in XML using java? -

i have piece of code generate xpath node. doesn't create array structure of it. example, if element has 2 elements same name, need provide index point them appropriately. illustration of below.

<abc>   <def>      </hij>   </def>   <def>      </lmn>   </def> </abc> 

now, xpath hij , need this:

//abc[1]/def[1]/hij 

to xpath lmn , need this:

//abc[1]/def[2]/lmn 

i have piece of code give me //abc/def/hij , //abc/def/lmn

private string getxpath(node root, string elementname)     {         (int = 0; < root.getchildnodes().getlength(); i++)         {             node node = root.getchildnodes().item(i);             if (node instanceof element)             {                 if (node.getnodename().equals(elementname))                 {                     return "\\" + node.getnodename();                 }                 else if (node.getchildnodes().getlength() > 0)                 {                     if(map.containskey(node.getnodename()))                         map.put(node.getnodename(), map.get(node.getnodename())+1);                     else                         map.put(node.getnodename(), 1);                      this.xpath = getxpath(node, elementname);                     if (this.xpath != null){                         return "\\" + node.getnodename() +"["+map.get(node.getnodename())+"]"+ this.xpath;                     }                 }             }         }          return null;     } 

can me append array structure this?

<abc>   <def>     </hij>   </def>   <def>     </lmn>   </def> </abc> 

in here. closing

</hij>  

and

</lmn> 

without opening them. if opening them before abc, them can't close them inside abc. basically: can't intertwince them. open one, open second, close second, close one. never in way around.

this might lead error
