Here is what I wrote. You might need to fine tune it. If you get a
better more efficient solution please do send me also. dataHash is the
hash table which will contain the data tags as keys and the values as
the value to be contained in the data. Also, I am yet not sure as to how
I am going to handle multiple tags. unless u put a number next to the
tag it will work. example
person, person1, person2 it will work.
Due to shortage of space I have deleted the windows methods
Thanks,
Ashoo
