Question

我有一个C＃程序，它通过SAS日志，我希望它提取错误的行。

例如，如果我的日志文件包含以下行：

WARNING: Apparent invocation of macro EDIT_TEXT not resolved.

ERROR 180-322: Statement is not valid or it is used out of proper order.

ERROR: SAS ended due to errors.
   You specified: OPTIONS ERRORABEND;.
ERROR: Errors printed on page 4.

NOTE: SAS Institute Inc., SAS Campus Drive, Cary, NC USA 27513-2414
NOTE: The SAS System used:
  real time           1.37 seconds
  cpu time            0.38 seconds

我想回来

ERROR: SAS ended due to errors. You specified: OPTIONS ERRORABEND;.
ERROR: Errors printed on page 4.

但它只返回

ERROR: SAS ended due to errors.

这是我正在使用的代码：

Match match;
Regex regex;
StreamReader sr;
string log;

sr = new StreamReader(path + ".log");
log = sr.ReadToEnd();
sr.Close();
regex = new Regex("ERROR: [^\\r]+\\r");
match = regex.Match(log);

我不确定在正则表达式上要更改什么来修复它。感谢

你可以尝试这个正则表达式。如果您有超过NOTE：或ERROR：，则应以类似的方式添加它们。

ERROR:(.*\n?.*)(NOTE:|ERROR:)?

此正则表达式包含存储在第1组中的错误信息。

其次，非正则表达式方法：

   string yourLogText = "you log text";

   string[] lines = yourLogText.Split(new string[1] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);
   string builtErrorText = "";
   Boolean isBuildingError = false;

   List<String> resultingErrors = new List<string>();
   for (int i = 0; i < lines.Length; i++)
   {
       if (lines[i].StartsWith("ERROR:"))
        {
          isBuildingError = true;

         if (!String.IsNullOrEmpty(builtErrorText))
               resultingErrors.Add(builtErrorText);

          builtErrorText = lines[i];
       }
       else if (lines[i].StartsWith("NOTE:") || lines[i].StartsWith("WARNING:"))
       {
            isBuildingError = false;
            if (!String.IsNullOrEmpty(builtErrorText))
                 resultingErrors.Add(builtErrorText);
       }
       else if (isBuildingError)
       {
           // If you want them to appear on different lines.
           builtErrorText += Environment.NewLine + lines[i];
        }
      }
    }

    // In case it ends with an error
    if (String.IsNullOrEmpty(builtErrorText))
        resultingErrors.Add(builtErrorText);

多行的正则表达式
