Regex to filter alphanumeric combinations

dougejm

Hi,

I am looking to filter out items not matching the requirements. I'm looking to keep items containing letters, numbers and special characters, it can be different combinations and I am struggling to get on regex code to match them all (or a simpler way to do it). If any help, each item will always be 3 characters or more.

Example what to keep/filter out:

abc123 (Letters and Numbers in any order = KEEP)

123456 (All numbers = KEEP)

abc-123 (Letters, special character, number in any order, length and any special character = KEEP)

abcdef (All Letters = OUT)

abc-efd (All letters and special characters in any order = OUT)

Hope this makes sense and thank you in advance

@dougejm I'm a little confused by the logic here. In your explanation you say 'filter out items containing letters, numbers and special characters', but in example 3, this is exactly that and you say it should be kept? From your examples, it looks like you want to filter anything where there aren't any numbers present - is that right? If that's the case then you can use a filter like so which just checks whether there's 1 (or more) occurrence of a digit:

REGEX_CountMatches([Input], '\d') > 0
