Thank you so much for all your valuable comments.

I need this in a single regular expression because one of all this formats will be there in the mail.

So bot should extract Wq1234567… format can any one of these and moreover i will be placing this regex in asset.

To be short, all this format should work in one regular expression.

(?i)\b(WQ|Q)[-\s]?\d{7,8}\b- this pattern extracts all except (- and / i.e WQ-12345678, WQ/1234567)

Please help
