Could please point out any approach that would be the best to achieve this ?
What have you tried? What was the result?
The approach I'd take would be to create a pseudo state machine that changes state based on input. If I was able to attach graphics to a PM post I'd give you a nice state diagram for that, but here goes with a text only version
start----->"TAGSTART" ---> intag ---> "TAGEND?" <------+
process input ---+
The bit "process input" you essentially read in a line, depending on the tag you just
add it to a hash as appropriate.
