java正则表达式获得内容中的图片

<span style="font-size:14px;">import java.util.regex.Matcher;import java.util.regex.Pattern;public class Test {public static void main(String[] args) { String urlRegex = "http://[^\":<>]*\\.(jpg|bmp|gif|ico|pcx|jpeg|tif|png)";        String urlStr = "[img]http://wew.sds.com/tee.jpg[/img]dfdf[img]http://wew.sds.com/tee23.jpg[/img]";  Pattern pattern2 = Pattern.compile( urlRegex, Pattern.CASE_INSENSITIVE );// 匹配表达式，忽略大小写          Matcher matcher2 = pattern.matcher( urlStr );          // 对匹配的集合进行循环处理，将文件保存到本地         while ( matcher2.find() ) {      System.out.println(matcher2.group(2));       } }}</span>

输出：
