global Variables help! seriously.....

[JayGTR]

Hi all, I got a global variable that I want to see the output for using trace.
The problem is it comes out blank when I do trace. It gets it data from an xml file. I don't see how it could not get data. If I put the trace inside the function it outputs a value but not outside the function. Must I make the function global or something? Please help!

code:

---

_global.xValue;

_global.userInfo = new XML();

_global.userInfo.ignoreWhite = true;

_global.userInfo.load("http://localhost/gBook/userInfo.xml");

_global.userInfo.onLoad =  function(success) {

 if(success)

 {

      var root = this.firstChild 

      var b=0;

      nodes = root.childNodes 

      for(var i=0; i<nodes.length; i++) {		 

            subnodes = nodes[0].childNodes 

            subnodes2 = nodes[1].childNodes

            subnodes3 = nodes[2].childNodes

            _global.xValue = subnodes[0].firstChild.toString() 

            _global.xValueOne  = subnodes2[0].firstChild.toString()

            _global.xValueOne2  = subnodes3[0].firstChild.toString()

    }

  }



}

trace("Global x: " + _global.xValue);

EDIT: Changed code tags to [ as ] tags - jbum

The problem is due to a misunderstanding of the order in which these lines execute.

At the time your trace() at the bottom executes, the onLoad() function has not yet executed, so _global.xValue has not been assigned from the XML yet.

The onLoad() function will execute later, and when it does, then _global.xValue will be defined.

So place your trace at the end of your onSuccess function
