提取文档中的指定内容

例子1：

while ((line = reader.readLine()) != null) {System.out.println(line);saveToFile(line, "reportlog.log", false);if (line.startsWith("INSTRUMENTATION_STATUS_CODE:")) {status ++;if (status == 2) {System.out.println(getCode(line));if (getCode(line).equalsIgnoreCase("-1")) {runresult = "运行错误";} else if (getCode(line).equalsIgnoreCase("-2")) {runresult = "断言错误";} else {runresult = "运行成功";}}}if (line.startsWith("INSTRUMENTATION_STATUS: stack=")) {//截取异常runinfo = line.substring(30, line.length());}if (line.startsWith("at student.Special.")) {//截取出错行errorlineinspecial = line.substring(line.indexOf(".")+1, line.length());}if (line.startsWith("at student.Case.")) {//截取出错行errorlineincase = line.substring(line.indexOf(".")+1, line.length());}if (line.startsWith("at student.Library.")) {//截取出错行errorlineinliabrary = line.substring(line.indexOf(".")+1, line.length());}}

例子2：
