I'm new to python, I wanted to know how to read a .txt file and the output should be in .xml format.

I have the input file as

  c) Option 1.c    d) Option 1.d

2. Text of question 2
  a) This is an example of Option 2.a
  b) Option 2.b has a special char α
  c) Option 2.c
  d) Option 2.d

3. Text of question 3
  a) Option 3.a can span multiple
  lines.
  b) Option 3b
  c) Option 3c
  d) Option 3d

Any suggestions?
