How to get the attribute out of an XML file

I have an XML like the below. I am able to use xml2struct (in the file exchange) to read the file. My question is how do I read the contents of "label" (DISSOLVED OXYGEN, pH) out of such files?

<datatypes>
     <datatype id="116" label="DISSOLVED OXYGEN"/>
     <datatype id="257" label="pH"/>
</datatypes>

Figured it out myself.

        xDOC = xml2struct('data/abc.xml');

        A = xDOC.datatypes.datatype;

        for i=1:length(A);
           dataType = A{i}.Attributes.label;
        end;
