regex matching for multi-line strings

[Emilian Ertel]

According to the documentation (https://docs.loganalytics.io/docs/Language-Reference/References/Regular-Expressions-syntax:(

"Flag syntax is xyz (set) or -xyz (clear) or xy-z (set xy, clear z)."

Unfortunately I did not find an example in the documentation on how to set the flags.

Example:

datatable(Message:string)

[

"Hello world",

"Hello

multi-line

world",

"foo bar"

]

| where Message matches regex "^Hello.*line.*$" 

returns no result because the m and s flags are not set.

The question is: how to set the "multi-line" (m) and the "dot matches newline" (s) flags in the query ?

Thank you in advance,

bye //emil.

The solution is:

| where Message matches regex "(?ms)^Hello.*\\s*.*line.*$"

Thanks Yoni !
