I think you just need to change the "" to '' like so:
dataProvider="{chartXML.lastResult.month.(@month_name=='01').day}"
However, you might be better off doing:
dataProvider="{chartXML.lastResult..month.(@month_name=='01').day}"
Here's a good quick reference too:
http://www.sephiroth.it/tutorials/flashPHP/E4X/page002.php
As a disclaimer, I have very little e4x experience but I presume that
it will get you where you need to go.
