Solution 1

Depends on the language you are using, but basically it's the same as you would do manually:

1) Read lines until you get one starting "CV ". When you find it create a new collection to hold the lines you wanted (or empty any existing collection)
2) Read lines until you get one that is "End". If it doesn't match, add it to a collection of some form.
3) When it does match, process the collection.
4) Go back to (1) for the next set of lines. until you run out of file.

With no idea what language you intend to write this in that's pretty much all we can do...

when you say collection are you referring to arrays? I need to extract the information next to the ":" character can I use a delimiter if I store each block of the file into an array?

An array is a collection, yes - but there are others. Arrays are a fixed size: once you create it you can't add of remove rows, so unless you know at the beginning how many "blocks" there are in your file - and that's not normally the case - it's best to look at other possibilities. For example, there is the ArrayList:
https://docs.oracle.com/javase/8/docs/api/java/util/ArrayList.html
Which allows you to expand it as needed (though at a cost).
