in reply to Remove line above matching criteria

You haven't shown us what you have tried so far, nor what your criteria for "best" are (fastest, least memory, simplest, etc). We cannot easily help you if you don't do your homework first.

From what you've given us, I'd egrep -v the data from the command line and skip perl altogether ...

    If you're going to go that route, you can also (with GNU grep, at least) grep -B 1 '<id:>' to get the ID line together with the previous line.

    It's all fine and dandy until someone has to look at the code.
