最近把软件发到google play苦于多国语言，手动翻译数量太多太蛋疼，于是用百度翻译api进行多国语言翻译。
不多说直接上代码；
"<string\\s*name=\\\"[\\s\\S]*\\\">";
匹配的是
<string name="app_name">Free 3D starter</string>中的<string name="app_name">
"(?<=\\\">)([\\S\\s]*?)(?=</)";
匹配的是<string name="app_name">Free 3D starter</string>中的<string name="app_name">
中的Free 3D starter
具体正则，大家自己去去理解哈，就不多说了。
