java 正则表达式匹配

需要匹配的文本内容形如：
words,"Reference": ["""words""","""words""","""words"""] words

words中可能包含任意字符，但不包含三引号。

我需要抽取[]中的内容，代码如下，结果是没有匹配
[code="java"]
reg = "\"Reference\": \[(^(\"\"\")*?)]";
pat = Pattern.compile(reg);
mat = pat.matcher(data);
if(mat.find())
{
System.out.println(mat.group());
System.out.println(mat.group(1));
}
[/code]

求指点

groovy 代码

[code="java"]
import java.util.regex.Pattern

text = "words,\"Reference\": [\"\"\"words1\"\"\",\"\"\"words2\"\"\",\"\"\"words3\"\"\"] words "

pattern = Pattern.compile("\"Reference\": \[(.+?)\]")
matcher = pattern.matcher(text)
while(matcher.find()) {
println matcher.group(1)
}

pattern2 = Pattern.compile("\"Reference\": \[((\"\"\"(.+?)\"\"\",?)+)\]")
m2 = pattern2.matcher(text)
while (m2.find()) {
for(i=0;i<=m2.groupCount();++i) {
println "group"+i+":"+m2.group(i)
}
}
