What is the problem? Please be detailed.
Need a function support string-before() and string-after(). I am fetching an ID from a CSV file which is in the format 000000-Name. I need to extract the numbers before '-'. please help
What ODK tool and version are you using? And on what device and operating system version?
Latest ODK on an android device
What steps can we take to reproduce the problem?
What you have you tried to fix the problem?
Using substring for now but doesn't solve the problem if length of ID changes.
Anything else we should know or have? If you have a test form or screenshots or logs, attach here.
