I wrote the following function
Function Get-StringBetweenStartEnd {
Param($Text,$Start,$End)
$Regex = [Regex]::new("(?<="+$Start+")(.*)(?="+$End+")")
$Match = $Regex.Match($String)
if($Match.Success) { Return $Match.Value}else{Return ""}
}
$Result = Get-StringBetweenStartEnd -Text $strInput -Start "<mail>" -End "</mail>"
write-host $Result.Trim()
The value is always null.
Any suggestion would be appreciated. Thanks in advance
By default, the . pattern does not match across multiple lines.
Enable single-line mode to change its behaviour:
Changes the meaning of the dot (.) so it matches every character (instead of every character except \n).
There are two ways to do it:
By specifying inline option s:
[Regex]::Match( $text, '(?s)<mail>(.*)</mail>' ).Groups.Value
By passing RegexOptions.Singleline to the Regex.Match method:
[Regex]::Match( $text, '<mail>(.*)</mail>',
[Text.RegularExpressions.RegexOptions]::Singleline ).Groups.Value
I took the liberty to simplify your RegEx by changing the lookbehind/lookahead assertions into simple patterns. Using a group to extract the value is simpler in this case.
Note that the static [Regex]::Match() method can be faster as it keeps a cache of compiled regular expressions and thus doesn't have to interpret the RegEx again when the same RegEx is used multiple times (e. g. in a loop).
