Ask nod for attribute

Question

Hi everyone,
got a problem. Need to ask in XML document if a nod has an attribute - if its declared. Is it possible? On some web I found "nod.HasAttribute" but it seems that is nod possible to use. Property missing.

Well I use XmlNode. foreach ( XmlNode n in dokument.SelectNodes( "/map/objekt" )) { if ( Here I need to ask if n has some attributes ) { objekty[i] = new GameObject ( new Vector2 ( Convert .ToSingle(n.Attributes[ "positionx" ].Value), Convert .ToSingle(n.Attributes[ "positiony" ].Value)), new Vector2 ( Convert .ToSingle(n.Attributes[ "targetpositionx" ].Value), Convert .ToSingle(n.Attributes[ "targetpositiony" ].Value) )); i++; } else { objekty[i] = new GameObject ( new Vector2 ( Convert .ToSingle(n.Attributes[ "positionx" ].Value), Convert .ToSingle(n.Attributes[ "positiony" ].Value))); i++; } }

The HasAttribute property exists for multiple classes, so it might help to mention what class you are using. It probably does not matter but it is a good thing to do to include details such as that. Have you verified that the node you think is the node is actually the node with the attribute? Problems such as you are encontering are often the result of assumptions that are not valid; the node might be a different node and if so then that would explain why the attribute is found. Something else I might do for diagnostic purposes is to use MoveToNextAttribute() to list the attributers for the node; that might show the problem or whatever.
