VbScript Regular Expression

[MarcusH]

Hi,

I'm having a problem with I VBScript regular expression.

I want to find FROM: xxxxx (where xxxxx is a number) when it is not proceded with TO: xxxxxx

So in

TO: 123456
FROM: 654321
FROM: 454545


I only want to find FROM: 454545 but I get FROM: 654321 as well.

The regular expression that I'm using is:

re.Pattern="(?!(TO:\s*\d+\s*))FROM:\s*\d+"

I've tried a slight variation on this which is:

re.Pattern="(?!TO:\s*\d+\s*)FROM:\s*\d+"

Your help would be very much appreciated.

Thanks
Marcus
