remove n lines before and after a specific text

[Rockberto Manenti]

Hi to all,
I am not at all an expert in notepad ++ and above all in commands to find and replace words or phrases within a text. I would like to be able to delete, on several files, some lines before and after a line that contains a specific word (but leaving everything else before and after) . Example:

text bla bla bla
bla bla bla
<actor>
<name> Chuck Profus </name>
<role> Drums </role>
<order> 5 </order>
<thumb></thumb>
</actor>
bla bla bla
bla bla bla

I’d like to delete 4 lines before and 1 after <thumb></thumb>
and must become in all the files:

text bla bla bla
bla bla bla
<thumb></thumb>
bla bla bla
bla bla bla

It can be done? Thanks in advance

You might try:

Find: (?-s)(?:.*?\R){4}^(.*?<thumb></thumb>.*?\R).*?\R
Repl: ${1}
Search mode: Regular expression
