Accessing a static XML variable from within a switch statement

In the following class

Code:

---

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

PHP Code:

---

</entitydefaults>;

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

try this:

PHP Code:

---

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:

http://bugs.adobe.com/jira/browse/ASC-2835

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

Code:

---

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.

Code:

---


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');

for the origin of the testing for existence of an XML attribute problem go here

@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.
