Hi,
I'm trying to use Node.hasAttributes to determine if an xml node has
attributes but I've got an issue using it :
if my node n is not an Element, the code below will throw an exception :
if(n.hasAttributes()){
// doing something with its attributes
}
throwing com.google.gwt.core.client.JavaScriptException: (TypeError):
jsObject.attributes is null
Of course I can catch this exception and deduct that this node has no
attributes but this is the goal of hasAttributes to determine it.
Then the hasAttributes implementation could be :
static native boolean hasAttributes(JavaScriptObject jsObject) /*-{
try{
return jsObject.attributes.length != 0;
}catch(exception){
return false;
}
}-*/;
By this way, asAttributes will always returns a result.
Is this a good idea or am I wrong in this use ?
