PyXB with XML schema containing choice statement

Vote count:

0

i am using pyXB for binding XML.

my schema used at there has choice elements.

so when i convert XML into a python instance

i don't know exactly which element is chosen at choice element.

So in order to distinguish, i have had to use if/else statement considering all cases.

for example, if the choice element has a and b, to distinguish one within a and b

A = binder.CreateFromDocument(xml)  #bind into a python instance

#At this point, i don't know which element is included
#So I have to check using if/else  
if A.a:
   #processing in the case of a
   A.a.aa = 'a'
else if A.b:
   #processing in the case of b
   A.b.bb = 'b'

the example is so simple and if/else looks enough but if the choice element has so many element about more than 100.

that processing(repeated if/else) will be so bad.

is there any other way to know which element is chosen?
