I'm sorry for being vague. I thought it was clear

Start by describing EXACTLY what your requirements are. No vagueness. For example "block of text" is actually a meaningless phrase. The whole document is a "block of text". The second sentence of a fifteen sentence paragraph is a "block of text". The entire paragraph is a "block of text". Four paragraphs together is a "block of text".
I see; actually, my document is divided in paragraphs that have the same structure. But in Word, every line of these paragraphs is also considered as a paragraph itself since there's a paragraph jump at the end of every line! That's why I thought it would be clearer if I used "block of text" to talk about the "big paragraphs".
Anyway, this is the kind of stuff I have to modify with my macro:

etc with loads of paragraphs like that (always the same tags and structure, but differents things between the tags, here I've written random letters of course)

And I want to delete the lines or groups of lines that start with certain tags, so that I get this (here I wrote them with bold characters so that you see which ones I want to keep, but of course, since it's XML code, in the original document there'll be no bold characters):
