[CS4-AS2] Remove undefined text

programming flash
1

Hello, All was working well until the xml changed. Sometimes the c_Result node in the xml doesn’t exist and my c_points text box returns ‘undefined’. I don’t know how to leave the c_points text box blank if the c_Result node doesn’t exist and load it if it does.
I have read loads of posts about this and have tried adding:
if(point != undefined){
} else {
c_points.text = “”;
}
But that doesn’t work, does anyone know the answer to this please?

AS2 CODE
import mx.styles.CSSStyleDeclaration;
_global.styles.TextArea = new CSSStyleDeclaration();

_global.styles.TextArea.setStyle(“backgroundColor” , “transparent”);
_global.styles.TextArea.setStyle(“borderStyle” , “none”);
_global.styles.TextArea.setStyle(“html”, “true”);

var str:String = “”;
var k:Number = 0;
var tmp:XML;
function loadXmlResults(){
xmlNode = this.firstChild;

str = (String(xmlNode.childNodes[1].firstChild)).split("<").join("<").split(">").join(">").split(""").join("\"");
tmp = new XML(str);
_country.text = tmp;

str = (String(xmlNode.childNodes[2].firstChild)).split("<").join("<").split(">").join(">").split(""").join("\"");
tmp = new XML(str);
_driver.text = tmp;

str = (String(xmlNode.childNodes[3].firstChild)).split("<").join("<").split(">").join(">").split(""").join("\"");
tmp = new XML(str);
_constructor.text = tmp;

}
