Regex

Question

Logic

Hi Everyone

I need a regex to validate don't contain only symbols and only symbols white space word, for example

"++----"---++())" or "===(())" Test.

I tried to use this

^[\.\+\-\*\/\,\'\;\]\}\[\{\&\^\%\$\?\\\s\#\@\!\~\-—`<>?]+(\s.*)*$,

but in outsystems it doesn't work.

Can anybody help me with this issue

Your regex only matches if a space is placed directly after a special character in your set (special characters or starts with a space):

.+-*/,';]}{()&^%$?\#@!~-`<>?

Wouldn't it be easier to do something like [^a-zA-Z0-9]?
This will match any character not present in a-z or A-Z or 0-9.

Next you matching on a space/whitespace character and any character after this.
This means your regex will match (SPECIALCHARACTERS)(SPACE/WHITESPACE)(ANYCHARACTER)

If your goal is to try and match ===(()) then your regex will not work.... instead something like:
^[^a-zA-Z0-9]+.*$

Will match your input, but then again, I'm not very sure what your goal is here, your text is a little bit confusing. (google translated from your native language into english perhaps?)

in that way i can have for example "???? ??????" and a-z doesn't contain these letters.

sorry I wrote in Armenian, I would say what can I do I case of for example Armenian or Russian letters

With my expression, it tooks the opposite

i want to get

+----mfkkffe44555

mkvvmveve+--*888

sdcdscdscdscs

kcsdokcodsc454/***ijscjsd

such words, but including Armenian letters and other letters too

Hey Gurgen10,

I can understand that, sorry.

As I said, your regex is working, but it might not be the intended result, what is the input and what is your desired output?

Again the following will match your regex :(SPECIALCHARACTERS)(SPACE/WHITESPACE)(ANYCHARACTER)

Hello,

I have tried Regex "^[a-zA-Z0-9]{4,10}+$" for Alphanumeric characters and its length should be between 4 to 10 although it is working fine in other regexes online compiler but throwing an error in outsystem by saying

"- Nested quantifier +" Why so??
