Regular expression to validate a specific pattern

Question

I'm trying to create a regular expression with the below restrictions

1. Allow any character '\w\W\s' (e.g rand123#!#@adfads)
2. Disallow only numbers (e.g 12312312)
3. Disallow only non alphanumeric characters (e.g !@#$$#%#^%$^%)
4. Number of characters must be between 3 to 60

Following along the lines of this answer, but could not get it work.

^(?=.{3,60}$)(?![\W_]*$)(?![0-9]*$)[\w\W\s]+$

Answer 1

Note that \W matches \s, so '\w\W\s' can be reduced to [\w\W].

You may use 2 negative lookaheads anchored at the start to impose two "disallow-only" conditions like this:

^(?![\W_]+$)(?![0-9]+$)[\w\W]{3,60}$

See the regex demo

Pattern details:

• ^ - start of string
• (?![\W_]+$) - the string cannot consist of non-alphanumeric chars
• (?![0-9]+$) - the string cannot consist of digits only
• [\w\W]{3,60} - 3 to 60 any characters
• $ - end of string.
