Hi All,

I am doing DOM integration with = spider=20 monkey. Below is one rapper api which gets called when we invoke var x = =3D=20 document.get_documentElement() from the java script. It is supposed to = return an=20 Element object. So x will contain an element object.

JSBool = get_documentElement(JSContext=20 *cx, JSObject *obj, uintN argc, jsval *argv, jsval=20 *rval){
Element*=20 tElem=3D&(doc.get_documentElement());//tmDoc
*rval=3DOBJECT_= TO_JSVAL(ConvertToJSObject(cx,element_methods,sEnv.elemObj,=20 (void*)tElem));
return JS_TRUE;
}

Now i invoke var y =3D = x.get_nodeName(); So the=20 corresponding wrapper functions get invoked. Element is inherited from=20 node.

JSBool get_nodeName(JSContext *cx, = JSObject *obj,=20 uintN argc, jsval *argv, jsval *rval){
XMLString=20 tXtr=3DGetNodePointer(cx,obj)->get_nodeName();
JSString*=20 tJStr=3DJS_NewString(cx,tXtr.GetBufferPointer(),tXtr.CharLength());
&n= bsp;*rval=3DSTRING_TO_JSVAL(tJStr);
return=20 JS_TRUE;
}

The problem here is that get_nodeName() = does not=20 return the proper XML string. I am supposed to get the name of the root = node.=20 Where as if i do the same operations i,e

Node *n =3D (Node *)tElem;
XMLString = tXtr=3D=20 n->get_nodeName();
char * data =3D = tXtr.GetBufferPointer();

in the function get_documentElement() i = get the=20 correct name.

The implementation of ConvertToJSObject = is given=20 below.

JSObject* ConvertToJSObject(JSContext*=20 cx,JSFunctionSpec* obj_methods, JSObject* jsProto, void* = data){

JSObject*=20 jsO;
jsO=3DJS_NewObject(cx,JS_GetClass(jsProto),jsProto,NULL); JS_DefineFunctions(cx,jsO,obj_methods);
JS_SetPrivate(cx= ,jsO,=20 (void*)data);
return jsO;
}

Thanx in advance,

Regards,

Pradip.
