Answer 1

测试代码

String html = "<a>www.baidu.com</a><a>www.qq.com</a><a>www.aaa.cn</a>www.eee.cn";
String reg = "www.*?(com|cn)";

Matcher matcher  = Pattern.compile(reg, Pattern.CASE_INSENSITIVE).matcher(html);
while (matcher.find()){
    System.out.println(matcher.group());
}

匹配输出结果

www.baidu.com
www.qq.com
www.aaa.cn
www.eee.cn
