如何在java中的引号之间获取数据？

Question

我有这行文字,引号的数量可能会改变如下:

Here just one "comillas"
But I also could have more "mas" values in "comillas" and that "is" the "trick"
I was thinking in a method that return "a" list of "words" that "are" between "comillas"

我如何获得结果应该是引号之间的数据？:

comillas
mas,comillas,trick
a,words,are,comillas

Answer 1

您可以使用正则表达式来捕获此类信息.

Pattern p = Pattern.compile("\"([^\"]*)\"");
Matcher m = p.matcher(line);
while (m.find()) {
  System.out.println(m.group(1));
}

此示例假定正在解析的行的语言不支持字符串文字中双引号的转义序列,包含跨越多个"行"的字符串,或支持字符串的其他分隔符(如单引号).

查看StringUtilsApache commons-lang库 - 它有一个substringsBetween方法.

String lineOfText = "if(getip(document.referrer)==\"www.eg.com\" || getip(document.referrer)==\"192.57.42.11\"";

String[] valuesInQuotes = StringUtils.substringsBetween(lineOfText , "\"", "\"");

assertThat(valuesInQuotes[0], is("www.eg.com"));
assertThat(valuesInQuotes[1], is("192.57.42.11"));
