XML gives me NaN in flex?

Try to read xml data into a variable to put it out in an

xml scheme

<akws>
<akw>
<name>test</name>
<_5>534543</_5>
</akw>
</akws>

now I want the number i开发者_StackOverflow社区n <_5> into an s:Label

private function countpop():void{   
popsum = parseInt(xmldata.akw[1]._5);
}

but

<s:Label text={popsum} />

gives me NaN?!

---

XML is zero indexed and also _5 is an element.

To refer to the int inside _5, use this code:

parseInt(xmldata.akw[0]._5[0]);

Here's my test to confirm:
