I have the following xml :

<Ingredients attribute="true">
    <Banana id="23" val="1" />
    <Flour val="0.96" />
    <Apple id="289055" val="0" />
</Result>

in an std::string xml and I am trying for instance to get the double value for the Flour attribute. I tried :

pugi::xml_document doc;
if (!doc.load(xml.c_str()))
    return false;
const pugi::xml_node floor = doc.child("Ingredients").child("Floor");

but floor‘s data member root has a NULL value at debug. How could I fetch the 0.96 ?
