用于筛选日志消息的RegExp

我已经有下面的代码创建了两个正则表达式(一个用于级别,一个用于文本),但我想知道如何将它们组合成一个。我尝试了几种组合,但由于我的regexp技能不存在,所以我无法实现这一点。

有什么提示吗?

代码:

private function filterLogMessage(item:Object):Boolean {
  var logMessage:String = String(item);
  var levelFilter:String = getLevelFilter();
  var levelRegExp:RegExp = new RegExp(levelFilter, "");
  var textFilter:String = StringUtils.trim(filterTextInput.text);
  var textRegExp:RegExp = new RegExp(textFilter, "");
  var match:Boolean = (levelRegExp.test(logMessage) && textRegExp.test(logMessage));
  return match;
}

private function getLevelFilter():String {
  var result:String = "";
  var selectedLevel:String = levelComboBox.selectedLabel;

  switch (selectedLevel) {
    case "DEBUG":
      //result = "\\[(DEBUG|INFO|WARN|ERROR|FATAL)\\]";
      break;
    case "INFO":
      result = "\\[(INFO|WARN|ERROR|FATAL)\\]";
      break;
    case "WARN":
      result = "\\[(WARN|ERROR|FATAL)\\]";
      break;
    case "ERROR":
      result = "\\[(ERROR|FATAL)\\]";
      break;
    case "FATAL":
      result = "\\[(FATAL)\\]";
      break;
    }

  return result;
}
