Android String字符串去除指定两个字符串范围内的字符

直接上代码
body-要修改的字符串 ，str1-要删除范围的首字符串，str2-要删除范围的尾字符串

 private String subRangeString(String body,String str1,String str2) {        while (true) {            int index1 = body.indexOf(str1);            if (index1 != -1) {                int index2 = body.indexOf(str2, index1);                if (index2 != -1) {//                    Log.e("Tag", "下标1为：" + index1 + "  下标2为:" + index2);                    String str3 = body.substring(0, index1) + body.substring(index2 +    str2.length(), body.length());//                    Log.e("Tag", "str3为：" + str3);                    body = str3;                }else {                    return body;                }            }else {                return body;            }        }    }

调用：

String body= "<p class=\"MsoNormal\" style=\"text-indent:21pt;\">\n" +                "\t<span style=\"font-family:微软雅黑;color:#3F3F3F;letter-spacing:0pt;font-size:10.5pt;\"> <span><span style=\"line-height:1.5;\"><span style=\"line-height:1;\"></span></span></span> </span> \n" +                "</p>\n" +                "<p class=\"MsoNormal\" style=\"text-indent:21pt;\">\n" +                "\t<span style=\"font-family:微软雅黑;color:#3F3F3F;letter-spacing:0pt;font-size:10.5pt;\"> </span> \n" +                "</p>";String str1 = "font-size";String str2 = "pt;";body=subRangeString(body,str1,str2);System.out.print("转化后为："+str);

输出结果：

转化后为：<p class="MsoNormal" style="text-indent:21pt;"><span style="font-family:微软雅黑;color:#3F3F3F;letter-spacing:0pt;"> <span><span style="line-height:1.5;"><span style="line-height:1;"></span></span></span> </span>                                                        </p><p class="MsoNormal" style="text-indent:21pt;"><span style="font-family:微软雅黑;color:#3F3F3F;letter-spacing:0pt;"> </span>                                                        </p>
