仅当分隔符被引号括起时，才在Java中拆分字符串

Question

Let's say I have the following string:

"John Doe","IT,SI","foo, bar"

And I would like to split it into:

["John Doe", "IT,SI", "foo, bar"]

I was thinking to implement something like this:

String line = "\"John Doe\",\"IT,SI\",\"foo, bar\"";
String[] lineItems = line.split("\",\"");

for (String lineItem : lineItems) {
    lineItem.removeAll("\"");
}

It does the thing, however this doesn't seem to be a state of art. Is there a better solution?

Answer 1

正则表达式适用于此案例。

String[] lineItems = line.split("(?<=\"),(?=\")");

Answer 2

以下内容应解决问题

line.split("(?<=\"),(?=\")") 

Answer 3

You wants the words between double quotes so instead of splitting the string you can use following regex to extract them :

/"([^"]+)"/g

See demo https://regex101.com/r/hC3cW2/1

Answer 4

(\b[^"]+)

Or you may name it also:

(?P<names>\b[^"]+)
OR
(?<names>\b[^"]+)

Not sure java supports P<> or <>
