Need help on getting the regexp working for text value of an item

[zabbixfk]

Hello All,

I am trying to build a trigger for an item which is producing text value.
Below is my item details.

Name - Windows Activation Status
Type - Zabbix Agent
Key - system.run[c:\Windows\System32\cscript.exe /nologo c:\Windows\System32\slmgr.vbs /xpr |more +1]
Type of information - Text
Update interval (in sec) - 86400
History storage period (in days) - 90
Applications - Activation Status
Description - This item outputs the activation status of the tied windows instance.

Now, as of now i am able to get two different values for this item depending upon the machine is activated or not.

If activated : The machine is permanently activated.
If not activated : Windows is in Notification mode

Considering , in case if i do not get exact string match of The machine is permanently activated., i need to generate alert, below is my trigger config,

Name - Windows is not Activated on {HOST.HOST} {HOST.IP}
Expression - {Windows_Activation_Check:system.run[c:\Windows\System32\cscript.exe /nologo c:\Windows\System32\slmgr.vbs /xpr |more +1].regexp(Windows is in Notification mode)}=1
Severity - Average
Enabled - yes.

But somehow i fail to understand how to get this regexp thing working, googled for some answers, but they landed up in matching text output with some number - for example, if a log as error count > 10 then alert etc.
Couldn't get any examples on exact string match using regexp for trigger expression.

It would be of great help if someone could explain how to get this regexp working in this example. Or on general text value match.

Thanks
