How to call a function located In an XML file

Hi i have XML file that do have number of items
each item have number of identifications like

<Category>
        <item
               type="English"
               FUNCTION_TO_Call = "English()">
        </item>
</Category>

as you can see that there is a text called English() defined in attribute Function_to_call

i was able tom get the text from XML file into my code using parsing method

but i don't fined any solution to instruct the program executor to call the function English() and run it

i use the following code

abc=kid.Function_to_call
abc()

it says that there is no reference available in abc()
but if i use

print kid.Function_to_call

i get what was saved in that attribute in XML file i get English() which is what i want to call for execution

is there any other method to do that
