When porting from AS2, you might find it more direct to use XMLDocument instead of XML. This behaves exactly like the AS2 XML object.
Having said that, I tried your code and it seemed to work (I assumed where you put node.childIndex() it was a typo and you meant to write _currentPage.childIndex()).
