Struggling with a regex challenge - need to validate two words with a mandatory point between them. No special characters, no @ symbol, and no spaces allowed. The format should be like this:
test.test
I've been attempting to use the following regex pattern without success:
^[a-z']*.[a-z']+$
If anyone could offer some assistance, I would greatly appreciate it. I've hit a roadblock and can't seem to figure it out on my own. Thank you in advance!
In the world of regular expressions, the dot serves as the wildcard operator and requires a backslash to escape it, like this: \.
For more information on wildcards and other common characters in regex, check out this Wikipedia page about Regular Expressions under the section titled "Basic Concepts".
To ensure the dot is treated as a literal dot and not a wildcard, use a backslash to escape it.
^[a-z']+\.[a-z']+$
In the realm of regular expressions, the dot (.) serves as a special character that matches any single character.
To interpret special characters literally, employ the backslash for escaping; for instance:
\\ (escapes the backslash)
\[ (escapes the bracket)
\{ (escapes the curly brace)
\. (escapes the dot)
