Http binding how to use correctly

Hi,
I need to get 4 digits token from website.
Website contains only 4 digits without any tag or .
I have tried couple of variations of item binding but without any result, can anyone help with this?
@.items
String token “[%s]” { http="<[http://192.168.0.134/temp:1000:REGEX((.*?))]" }
@.sitemap
Text item=token

So are you getting more than expected or nothing at all?

Any errors in the logs?
