Help
1

Hi. I have had a lot og progress with my programming thanks to you. Not I am looking for a way in for each to pass an empty string.
In array I can have multiple string wich starts with a date, but how to pass if the strings is missing or does not start with a date= I am only interestet in the strings that contain a date.
Like myArray
string(0) “Empty”
String(1) 04-11-19 bla bla bla
String(2) 04-11-19 bla bla bla
String(3) bla bla bla

Not always in this ordre, may change.
I have used regex to find date: “[0-9]{2}-[a-z]{3,}-[0-9]{2}”
Works fine, also my other regex forks fine, thanks to help from you. Strings starts with date I read fine and result is ok, but prosess stops when it read strings who does not start with date, I am as I said not interested in them.

Regards Kåre

Hi @kare.smorvik
Based on For each item in My Array

Check the condition like String.IsNullOrEmpty(item.ToString) or String.IsNullOrWhiteSpace(item.ToString)

Thanks

You can use an inline if statement to set the value to string.empty if the regex does not find a value. This is untested code so you may have to fix some minor issue, but it would be something like this: If(Regex.IsMatch(InputString,"[0-9]{2}-[a-z]{3,}-[0-9]{2}"),Regex.Match(InputString,"[0-9]{2}-[a-z]{3,}-[0-9]{2}").Value,string.Empty)

This first checks if a match is found. If it is found, it gets the string value. If no match is found, it gives a an empty string
