I have a case where I need to parse a string into several groups depending on a criteria

For example the below;

01%3A%35r%07%01P%88%00;WAP_GPRS

should be 2 groups

%3A%35r%07%01P%88%00
WAP_GPRS

Notice that I dont care about 01 at the beginning and there can be 0 or more substrings delimited by ; and I need them all in their own group.

Another one;

01%3A%35r%07%01P%88%00;KPN;A23B

should be 3 groups:

%3A%35r%07%01P%88%00
KPN
A23B

Basically, I dont need to care if alpha or numeric comes first. The issue is grouping expressions into their own which can be 0 or more times. Meaning the below

01%3A%35r%07%01P%88%00

should produce also one group of %3A%35r%07%01P%88%00

    So I guess you need a regexp analog of split. That would require a repeated capturing group.

    Bad news, some people have looked into a similar problem and haven’t found the right answer:

    Good news, if you can live with some reasonable limit on the number of groups and you can add some code to identify the empty trailing ones, this may help:

    ([^;]*);?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?;?([^;]*)?
