In a file containing tags like these:
<div class="myclass"> Something irrelevant. </div> <div class="myclass"> MATCH ME </div>
I would like to delete all tags not containing a specific pattern, here "MATCH ME" as an example. I can search for the opening of the tag, then do
vat, inspect the selection, if it doesn't contain my pattern I hit
d to delete it and move on to the next candidate with
n, else I will hit
n straight, continuing to the end of the file. Now I'd like to automate that, as I have a few files like that. How?
