paragraph wildcard

[gordon....@gmail.com]

is there a paragraph character or wildcard?

[RSF]

Generally the regular-expression

    \n

should indicate a "newline" character, which generally equals the end of a paragraph -- if the text being inspected is formatted as a continuous string of characters separated by newlines at the end of paragraphs...

If text is instead formatted with a newline character at the end of each line, and a blank line indicates a new paragraph, then the regular expression

    ^$

could be used to find those blank lines.

https://regex101.com/ is a good place to experiment with regular expressions; you can paste your text there, and try different regular expressions to see which will work.
