Accessing a static XML variable from within a switch statement

[justkevin]

In the following class

package
{
	public class Factory
	{
		public static var myXML:XML;
		
		public function Factory()
		{
		}
		
		public static function staticTest(varName:String)
		{
		switch(varName)
			{
				default:
				Factory.myXML = <entitydefaults>
				<entity id='DRONE' points='100'></entity>
				<entity id='BOMBER' points='1000'>
				</entity>
				</entitydefaults>
				var x1 = Factory.myXML.entity.(@id == 'DRONE');
				var x2 = Factory.myXML.entity.(@id == 'DRONE');
				trace('okay');
			}
		}

	}
}

A break point on the "Okay" line shows that x1 is null but x2 is equal to "<entity id="DRONE" points="100"/>".

If I take the whole block out of the switch statement, both x1 and x2 are equal to the expected xml.

Why?

try terminating your inline xml with a semicolon

</entitydefaults>;

Thanks for the suggestion, but that didn't help.

try this:

package
{
    public class Factory
    {
        public static var myXML:XML;
        
        public function Factory()
        {
        }
        
        public static function staticTest(varName:String)
        {
        var x1,x2;
        switch(varName)
            {
                default:
                Factory.myXML = <entitydefaults>
                <entity id='DRONE' points='100'></entity>
                <entity id='BOMBER' points='1000'>
                </entity>
                </entitydefaults>
                x1 = Factory.myXML.entity.(@id == 'DRONE');
                x2 = Factory.myXML.entity.(@id == 'DRONE');
                trace('okay');
            }
        }

    }
}

Looks like this is actually one of those rare cases where the bug isn't in the code, it's in the AS3 VM:

someone else had the same problem with testing for existence of an XML attribute. He thought he could type

var postNodes:XMLList = my_xml2.viewentry.entrydata.(@category != undefined);

You have to go through the XML to find what your looking for. I came up with this on the timeline.

var myXML:XML = new XML();

function staticTest(varName:String){;

myXML=XML('<entitydefaults><entity id="DRONE" points="100"></entity><entity id="BOMBER" points="1000"></entity></entitydefaults>');

var xmllistamount:int=myXML.entity.length()-1;

for (var i:int = 0; i<=xmllistamount; i++) {
	
	var varname:String=myXML.entity[i].@id;
	
	switch (varname) {
		
		case 'DRONE' :
			trace(myXML.entity[i].@points);
			break;

		case 'BOMBER' :
			trace(myXML.entity[i].@points);
			break;

		default :
			trace('okay');
			break;
	}
}
}

staticTest('o');

@justkevin: declaring the variable before the switch (but instantiating in the case... as per the last example i posted) worked for me. and the link you posted says encasing the case statement in curlies is a valid workaround too. but yeah, you're right - it's wierd.

@onenterframe: i think that's a different issue than the one justkevin is experiencing.
