I need help with forming the regex for reading a file following the structure:
2050206,"Abella, Jan Vincent P",BSECE,1,Male
How can I ignore the comma inside the double parenthesis? Thank you in advance
Here is an example of how to split on a comma by passing a regex to split .
The negative lookahead (?![^"]*"[^"]*$)
prevents a comma being matched if there is only one "
ahead in the line.
(?m)
turns on MULTILINE mode so that $
matches the end of a line and not the end of the whole string.
public class Example {
public static void main(String[] args) {
String string =
"2050206,\"Abella, Jan Vincent P\",BSECE,1,Male\n" +
"2050207,\"Theron, Charlize\",BSECE,2,Female";
String regex = "(?m),(?![^\"]*\"[^\"]*$)";
for (String s : string.split(regex)) {
System.out.println(s);
}
}
}
Prints:
2050206
"Abella, Jan Vincent P"
BSECE
1
Male
2050207
"Theron, Charlize"
BSECE
2
Female
