替换内容

Question

怎么用正则实现
<img src=\"/images/306.gif\"/>dd<img src=\"/images/309.gif\"/><img src=\"/images/307.gif\"/>
替换为
[img src=\"/images/306.gif\"/]dd[img src=\"/images/309.gif\"/][img src=\"/images/307.gif\"/]

Answer 1

正则我是不会啦，我只会下面的方法
String str1="<img src=\"/images/306.gif\"/>dd<img src=\"/images/309.gif\"/><img src=\"/images/307.gif\"/>";
String str2=str1.replaceAll("<","[");
String str3=str2.replaceAll(">","]");
