PowerShell comes with great support for regular expressions but the -match operator can only find the first occurrence of a pattern. To find all occurrences, you can use the .NET RegEx type. Here is a sample:
$text = 'multiple emails like tobias.weltner@email.de and tobias@powershell.de in a string' $emailpattern = '(?i)\b([A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4})\b' $emails = ([regex]$emailpattern).Matches($text) | ForEach-Object { $_.Groups[1].Value } $emails[0] "*" * 100 $emails
Note the statement "(?i)" in the regular expression pattern description. The RegEx object by default works case-sensitive. To ignore case, use this control statement.
