basically needed parent tag should removed , childs should immideate child of root.

logic part

node root = doc.getelementsbytagname("ns0:emessage").item(0);  nodelist listofnodes = root.getchildnodes(); int length_child_nodes=listofnodes.getlength(); system.out.println("length of child nodes root element"+length_child_nodes); (int = 0; < listofnodes.getlength(); i++) {     //  node picked in click , element , have childs.     node listitem = listofnodes.item(i);     node fchild=listitem.getfirstchild();     string value="";     if ("ns0:name".equals(fchild.getnodename())) {         node oldchildnodename=listitem.getfirstchild();         node value=fchild.getnextsibling();         if("ns0:value".equals(fchild.getnextsibling().getnodename())){             value=fchild.getnextsibling().gettextcontent();         }         string localname=listitem.getfirstchild().gettextcontent();         element newchildnode = doc.createelement(localname);         //  replace existing node property name.         listitem.replacechild(newchildnode, oldchildnodeprpertyname);         //                  replace existing node property value         listitem.removechild(value);         //system.out.println("remove child"+node.removechild(oldchildnodepropertyvalue));         newchildnode.settextcontent(value);         //system.out.println("new node name::"+newchildnode.getname());         //system.out.println("old node::"+oldchildnodeprpertyname.getname());         //system.out.println("newvalue::"+newchildnode.gettextcontent());     } } 

the above code manipulation required.but parent of childs tag needed removed.which not getting through.and ideas great me.
