android string 去掉字符,android – 如何从字符串中删除动态字符串？

我是

Android开发的菜鸟,我试图从字符串中删除一串动态字符.我的字符串：

"Beginning of String....<img src="http://webaddress.com" height="1" width="1"/>"

我想删除“& lt”,“& gt”以及它们之间的所有内容.我想要的只是“字符串的开头……”到目前为止,我已经尝试过这个并没有成功.

description = description.replaceFirst("(?s)(&lt)(.*?)(&gt)","$1$3");

此外,我尝试了类似的类似字符串,它工作正常,所以我不明白我做错了什么.

description = description.replaceFirst("(?s)(_)(.*?)()","$1$3");
