crossscript and javascript regular expression match and split

Hi,

i like to grep the hexnumber from the buildnum.h file i tryed it with split and with match but both give me undefined back.

buildnum.h contens: #define BUILDNUMBER 0x01080000  /*version    - fill it here*/ 

the script file:   var file = "buildnum.h";   var text = "#define BUILDNUMBER 0x";   var s = CWSys.readStringFromFile(file);   var n;   if (s == undefined)     n = 1;   else //  n = eval(s.substring(text.length)) + 1; //  n = s.split(" "); //  n = eval(n[2]);

result = s.match("/\b0[xX][0-9a-fA-F]+\b/g");   CWSys.writeStringToFile(file, text + result + "  /*version    - fill it here*/  \r\n");
