regex: Select all lines that do not end with a specific tag

Question

I have this 4 lines, all starting with tag <p class="TEST"> and ending with tag <br> except the last two.

<p class="TEST">My mother is at home.<br>
<p class="TEST">My father is at home.<br>
<p class="TEXT">My sister is at home.<LLbr>
<p class="TEXT">My brother is at home.<AAbr>

So, I want to find all lines with TEXT tag that doesn't ending with <br>

My output result should be

<p class="TEXT">My sister is at home.<LLbr>
<p class="TEXT">My brother is at home.<AAbr>

I made a regex, but is not too good. (?-s)(.*<p class="TEXT">.*)(?-s)(?!)<br>(.*)$

Answer 1

• Ctrl+H
• Find what: <p class="TEXT">(?:(?!<br>)(?!<p).)*(?:<.+?>|\z)
• UNcheck Match case
• check Wrap around
• check Regular expression
• UNCHECK . matches newline
• Search in document

Explanation:

<p class="TEXT">    # literally
(?:                 # start non capture group
  (?!<br>)          # negative lookahead, make sure we haven't <br>
  (?!<p)            # negative lookahead, make sure we haven't <p
  .                 # any character but newline
)*                  # group may appear 0 or more times
(?:                 # non capture group
   <.+?>            # a tag
 |                  # OR
   \z               # end of string
)                   # end of group
