Regex to find two words on the page

Question

I\'m trying to find all pages which contain words \"text1\" and \"text2\". My regex:

text1(.|\\n)*text2 

it doesn\'t work..

Answer 1

If your IDE supports the s (single-line) flag (so the . character can match newlines), you can search for your items with:

(text1).*(text2)|\2.*\1

Example with s flag

If the IDE does not support the s flag, you will need to use [\s\S] in place of .:

(text1)[\s\S]*(text2)|\2[\s\S]*\1

Example with [\s\S]

Some languages use $1 and $2 in place of \1 and \2, so you may need to change that.

EDIT:

Alternately, if you want to simply match that a file contains both strings (but not actually select anything), you can utilize look-aheads:

(?s)^(?=.*?text1)(?=.*?text2)

This doesn't care about the order (or number) of the arguments, and for each additional text that you want to search for, you simply append another (?=.*?text_here). This approach is nice, since you can even include regex instead of just plain strings.
