Skip commas in brackets regexp

Hi All

I am trying to split a string, but need to skip strings within brackets, and keep this as one entity. How can I split the following

A,VC,D,XO(12,13,14,15),DX,DY

using strsplit, so that XO(12,13,14,15) is not split at the commas. I would therefore like to ignore the content inside the brackets.

Any help would be appreciated.

Is nesting of brackets permitted? If so that makes it much harder.

S = 'A,VC,D,XO(12,13,14,15),DX,DY';
regexp(S,'\w+(\([^)]+\))?', 'match')

Thanks Walter. Works a treat.

Hi Walter

I have to say that I am very confused by how regexp works. How would I split the following:

str = 'DATA,F,[11*0.D0,4.34255D0,-1.14281D0]'

to only split by the commas outside of the brackets?

Regards

regexp(str,'\w*([\(\[][^\)\]]*[\)\]])?', 'match')

appears to work for both this case and the previous case.
