</QuestionTable>

NOW I WANT TO EXTRACT THE DATA FROM IT AND PUT THAT IN SEPARATE ARRAY FOR EACH TYPE i.e.
string[] qArray,o1Array,o2Array,o3Array,o4Array;
qArray[] will Contain all Data inside <q> and </q>
o1Array[] will Contain all Data inside< o1> and </o1>
etc.
I think splitstring method along with regXwill do that but I cant do that.
Can Anyone Help me.
