So you could set the string expression to something like this: 

STREAM::expression {@[^<]+@@}

And use that in an iRule: 


when HTTP_REQUEST {
    Disable the stream filter for all requests
   STREAM::disable
}
when HTTP_RESPONSE {

    Check if response type is text
   if {[HTTP::header value Content-Type] contains "text"}{

      STREAM::expression {@[^<]+@@}

       Enable the stream filter for this response only
      STREAM::enable
   }
}
