So in VS Code I used this <script>(.|\n)*?<\/script> regex pattern to select everything between <script> tags (including tags) and it worked great. (See the example below)
<html>
<p>dsldsdsd</p>
<p>dsldsdsd</p>
<p>dsldsdsd</p>
*<script>
Some code
</script>*
*<script>
Some code
</script>*
<p>dsldsdsd<p>
<p>dsldsdsd<p>
</html>
So with this <script>(.|\n)*?<\/script> everything between * * gets selected.
Now what I actually want to do is do the opposite of what I've shown you. For example, like this. Select everything else but leave inside<script> </script>tags. (Along with the tag)
*<html>
<p>dsldsdsd</p>
<p>dsldsdsd</p>
<p>dsldsdsd</p>*
<script>
Some code
</script>
<script>
Some code
</script>
*<p>dsldsdsd</p>
<p>dsldsdsd</p>
</html>*
So I went through some regex documents online and I tried the following regex to select everything else (and keep everything between <script> tags)
^((?!<script>(.|\n)*?<\/script>).)*$
But this just keeps the word <script>. What have I done wrong?
In short, what I'm trying to do is negate the <script>(.|\n)*?<\/script> expression.
Any help is appreciated. Thanks.

An idea is to match what you don't want but capture what you need to \1
<script>[\s\S]*?<\/script>|((?:<(?!script)|[^<])[\s\S]*?)(?=<script|$)
See this demo at regex101
To not skip over an opening <script in the alternation either match a character, that is not < or match a < which is not followed by script by use of a lookahead until <script occurs or $ end.
