Question

我正在尝试将异常加载到字段“Exception_type”，以便我可以在我的应用程序上显示它。我有一个正则表达式，但它给了我多个匹配组。我需要的是“Exception_type”字段上的完整消息。如果你能提供帮助，请复制。

正则表达式：

(?<Exception_type>[a-zA-Z]+.*[^,]*[^ ,][^,]*$)

Answer 1

您可以使用

(?s)^\S+\s+\S+\s+(?<Exception_type>.*$)

请参阅regex demo

^\S+\s+\S+\s+匹配用1个空格分隔的前2个非空格块文本，其余部分捕获到组1中。

要删除GUID，您需要使用第二步：

\b[a-fA-F0-9]{8}(?:-[a-fA-F0-9]{4}){3}-[a-fA-F0-9]{12}\b

请参阅regex demo，替换为空字符串。

此处，\b是字边界，[a-fA-F0-9]与十六进制字符匹配。
