I want to split a pipe( | ) delimited file using regex only and extract a particular field at nth position. My current solutions works fine until a blank field appears. I am unable to figure out what i am doing wrong.

Sample Data:

asdw|qwe|23344|as||sada||ssss|sdd

My partially working solution:

^((?:[^|] \|){3})(?P<error>[^|] )

CodePudding user response：

Just need to swap the 'One or more token ' with a 'Zero or more token *' as it looks like it's getting stuck with no chars between the two pipes.

I think the following should give you the result you are looking for:

^((?:[^|]*\|){3})(?P<error>[^|] )
