Can I know one element under a parent node existence?
If my xml file's content like this:

<?xml version="1.0" encoding="utf-8"?>
<loader value="../../../asset/art/demo25Dv1.swf"/>
<video width="1280" height="720"/>

<touch>
    <show_points_info/>
</touch>

When I use ptree.count("touch"), it returns 1.
But I use ptree.count("touch.show_points_info"), it returns 0 instead.
What's wrong with that? Or should I use another method to get existence node
of any depth?
