急,怎么用java写一个正则表达式，去匹配<BUTTON name=''>test</BUTTON>

Question

怎么用java写一个正则表达式，去匹配test，取出test这个值，替换test, ,例如
it is a test, THIS IS Alink..

并且取出test,link的等值, 匹配之后要求的效果是
it is a test,THIS IS A link.
[b]问题补充：[/b]
如果再把这个正则改成 test，要求把 替换成空格。
it is a test, THIS IS A link..

替成：
it is a test,THIS IS A link。请回答，感激不尽。

[code="java"]public class Demo {
public static void main(String[] args) {
String str = "it is a test, THIS IS A link..";
String result = str.replaceAll("(.*?)", "$1");
System.out.println(result); // it is a test, THIS IS A link..
}
}[/code]
楼主是要这样？
