regular expression to remove all other words except the words between special characters in notepad++

I am trying to create a regex in Notepad++ to remove words except those enclosed between special characters. I am using this regex \<.*?\> which removes the words along with text.

Eg:
Sample text

random text <ABCD> random text
random text <QWERT> random text
random text <XYZ> random text

Output

random text random text
random text random text
random text random text

I just want the opposite of the above regex

Eg:
Sample text

random text <ABCD> random text
random text <QWERT> random text
random text <XYZ> random text

Output

<ABCD>
<QWERT>
<XYZ>

This is a job for (*SKIP)(*FAIL) verbs.

• Ctrl+H
• Find what: <.+?>(*SKIP)(*FAIL)|.+?
• Replace with: LEAVE EMPTY
• TICK Wrap around
• SELECT Regular expression
• UNTICK . matches newline
• Replace all

Explanation:

<.+?>       # matches the string to be kept
(*SKIP)     # skip this match
(*FAIL)     # considere it failed
  |           # OR
.+?         # match any character but newline
