<ARR>20080625<ARR><DEP>20110606<DEP><PCIID>626783<PCIID><NOPAX>1<NOPAX><TG><TG><HASPREV>FALSE<HASPREV><HASSUCC>FALSE<HASSUCC>

任何人都可以帮我找出我需要在表达式中进行哪些更改以保留结束标记 </tag>

Private Function CleanInput(ByVal inputXML As String) As String
    ' Note - This will perform better if you compile the Regex and use a reference to it.
    ' That assumes it will still be memory-resident the next time it is invoked.
    ' Replace invalid characters with empty strings.
    Return Regex.Replace(inputXML, "[^><\w\.@-]", "")
End Function

Answer 1

Private Function CleanInput(ByVal inputXML As String) As String
    Return Regex.Replace(inputXML, "[^/><\w\.@-]", "")
    ' --------------------------------^
End Function

但由于您的目标只是删除\04和 ，\00因此仅限制对它们的替换会更安全。

Private Function CleanInput(ByVal inputXML As String) As String
    Return Regex.Replace(inputXML, "[\4\0]", "")
End Function
