<![CDATA[Regex: Delete all lines containing characters other than [a-z], [A-Z], and [-]]]>Hello.

Thanks again in advance:

I have a list and I want to delete every line, which contains a character which is not
[a-z], [A-Z], and [-].

so:
bl-a
bla
blà
bl%
blo
bló
blO

should become

bl-a
bla
blo

Thank you very much!

Use the following regex S/R :

SEARCH ^.*[^A-Za-z\r\n-].*\R

REPLACE Leave EMPTY

Notes :

  • The ^ symbol ,beginning the character class, is the negation character

  • The - symbol must be located at the end of the character class as it’s a special** char inside class character

  • The \R syntax matches any kind of line-break

Best Regards
