Dear @janna, dear @Xiphware, dear @tinok,
Let me add a very simple example which works differently on KoBoCollect
regex(., ‘[a]+’)
Attachment with some more variants
ARegexCollect01.xlsx (12.8 KB)
RegEx tool
Screenshot Collect (after entered Ba)
Again Preview/Enketo does what is expected, but KoBoCollect allows only a (1-n times), nothing else. Collect treats the regex like regex(., ‘^[a]+$’).
(I didn’t find any documentation or explanation for this behavior.)
Waiting for your expert feedback, please.
Best regards
