how to get data between quotes in java?

I have this lines of text the number of quotes could change like:

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"

How I obtain the data between the quotes?

The result should be:

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

Solution 1:

You can use a regular expression to fish out this sort of information.

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

This example assumes that the language of the line being parsed doesn't support escape sequences for double-quotes within string literals, contain strings that span multiple "lines", or support other delimiters for strings like a single-quote.

Solution 2:

Check out StringUtils in the Apache commons-lang library - it has a substringsBetween method.

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"));

Solution 3:

String line = "if(getip(document.referrer)==\"www.eg.com\" || getip(document.referrer)==\"192.57.42.11\"";
StringTokenizer stk = new StringTokenizer(line, "\"");
stk.nextToken();
String egStr = stk.nextToken();
stk.nextToken();
String ipStr = stk.nextToken();

Solution 4:

Firstly, please note that you should user equals() rather than ==. "==" by default asks if they are the same instance in memory, which in Strings can sometimes be the case. With myString.equals("...") you're comparing the values of the Strings.

As for how do you obtain the values between the quotes I'm not sure what you mean. "..." is an actual object. Alternatively you could do:

String webUrl = "www.eg.com";
