Help with Aggregate/Multiline

[TehMuffinMoo]

I'm looking to the community to hopefully shed some light on how I can achieve this. I've got some unstructured multi-line data with a definitive start and end event. I'm struggling to figure out if I should be using Multiline, Aggregate or both.

I'd like to for each line either capture the value or drop the line. I'm only bothered about the 1st, 6th & 7th lines and ideally aggregate the two multi-line sections into a single field.
