Import custom ascii format from file

I need to import an ascii file with a custom file-format.

Some data is stored in blocks, with a start block and end block. Other data is stored without block delimiters.

One example is:
$Sheet
S posx posy dimx dimy
List of Sheet Labels
$EndSheet

Another is:
Text Notes posx posy orientation dimension ~
Text

Now what would be the best/most generic way to import these data into some kind of structure?

Regards

You're going to need to read a line: if it's a block start then hand off to a method that will handle a block read. If it's not, then hand off to a method that will handle a non-block read.

The most "generic" way to do that is to have a factory method that returns you the requisite Reader class. Some pseudo code might look like this:

Open [File]
while not EOF
  Read [Line]
  var [Reader] = ReaderFactory.GetReader([Line])
  var [Record] = [Reader].Read([File])
  Do what you want with record
wend
Close [File]

How you represent the different record types I leave as an exercise for you :)
