IfMatch with special characters

[Jaime Méndez]

Hello!

How can i use "RegExpSubstitute" to ask for exact match of a string containing only 3 characters like "C:\"

MeasureName=DiskName
IfMacht=C:\ | D:\ | E:\
IfMachtAction=[DoSomting]

The "\" character is a reserved character in Regular Expression. It means "escape the next character and treat it as a literal rather than a reserved character." So to specify a literal "\" in a search parameter, you have to "escape" it, like this:

Code: Select all

IfMatch=C:\\|D:\\|E:\\
IfMatchAction=[!Log "Yessir, that's my baby. Nosir, I don't mean maybe"]

JSMorely beat me but I will leave my suggestions...

That's not RegExpSubstitute, you posted an IfMatch RegExpression test... but that is not important.

The string you are testing contains a reserved character \ (backslash) so you need to either "escape" that with another backslash or use :EscapeRegExp section variable.

This code manually escapes the backslash and disregards string case. (?i) will match any drive letter defined regardless of the string case.

Code: Select all

[MeasureDiskName]
Measure=String
String=[DiskName]
IfMatch=(?i)C:\\|D:\\|E:\\
IfMachtAction=[DoSomething]

This code automatically escapes reserved characters and disregards string case. (?i) will match any drive letter defined regardless of the string case.

Code: Select all

[MeasureDiskName]
Measure=String
String=[DiskName:EscapeRegExp]
IfMatch=(?i)C:\|D:\|E:\
IfMachtAction=[DoSomething]
DynamicVariables=1

Notice DynamicVariables=1 must be used with section variables.

Thank you both! It was easer than i thought
