协助正则表达

Question

我有一个文件，其格式如下所示。 #ADDBANK是每条记录的标题，每条记录可能有0行或多行以//错误开头！

我需要一个正则表达式来识别包含1个或多个以//错误开头的行的所有记录（以#ADDBANK开头）！并从该记录返回以下行：

• 包含#ADDBANK
的行
• 相应记录中以customerNumber
开头的行
• 记录中以// error！
开头的每一行

例如，对于具有以下两个样本记录的文件的正则表达式的结果，将如下所示。那里的任何正规表达专家都可以借给我一个手？

结果

#ADDBANK
customerNumber=10427856
//error!-error=SP02195:account.paymentSummary.statementFormat is not required when account.paymentSummary.statementIndicator is Suppress Statement-Create Billing. error=SP02195:account.paymentSummary.statementFormat is not required when account.paymentSummary.statementIndicator is Suppress Statement-Create Billing.
//error!-error=ufaEvent.process exception : account.paymentSummary.statementFormat is not required when account.paymentSummary.statementIndicator is Suppress Statement-Create Billing. error=ufaEvent.process exception : account.paymentSummary.statementFormat is not required when account.paymentSummary.statementIndicator is Suppress Statement-Create Billing.

Answer 1

如果您希望匹配这些行，您只需匹配每行的结尾即可。使用这个正则表达式

#ADDBANK|customerNumber.*|\/\/error.*

您将匹配记录中的所有必需行。但是使用这个正则表达式，你将不得不遍历所有匹配，以收集所有匹配的行。
