Hi All,
Is it possible to split the file name and get the outputs shown below.  

140357-XXXX_r1414_WP-book8_994x1163_CMYK_v2

output: 140357-XXXX

140357-XXXX-141863_r1414_AS2-BRAND-WALL-GPF2_3000x1285_CMYK_v2

output: 140357-XXXX

140357_r1414_WP-book8_994x1163_CMYK__XXXX_v2

output: 140357-XXXX

141863_r1414_AS2-TEST-BOOK-GPF2_3000x1285_CMYK_140357__XXXX_v2

Sure. String.split(separator) returns an array of strings broken up by the separator, excluding the separator.

Your first example is: 

var ns = myDoc.name.split("-");

ns = ns[0] + "-" + ns[1].split("_")[0];

Your second example is: 

var ns = myDoc.name.split("-");

ns = ns[0] + "-" + ns[1];

Third example is:

var ns = myDoc.name.split("_");

ns = ns[0] + "-" + ns[6]; //double underscore is split twice, with first instance of split being an empty string

Fourth example is:

var ns = myDoc.name.split("_");

ns = ns[5] + "-" + ns[7]; //double underscore is split twice, with first instance of split being an empty string
