Regex on STREAM expression

Hi,

I'm trying perform a regex on a STREAM::expression, is something like this possible?

{@EXT.1920x1080.(.|\n)*@@}

Here is an example of the text:

EXT-X-STREAM-INF:BANDWIDTH=4950570,RESOLUTION=1280x720,CODECS="avc1.4D401F,mp4a.40.2" manifest_7.m3u8 EXT-X-STREAM-INF:BANDWIDTH=6600279,RESOLUTION=1920x1080,CODECS="avc1.64002A,mp4a.40.2" manifest_8.m3u8

When I run the regex in notepad++ it selects the desired text, but doesn't seem to work on the F5.

Here is my irule:

when HTTP_REQUEST {

  STREAM::disable
  HTTP::header remove "Accept-Encoding"

}

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

STREAM::expression {@EXT.*1920x1080.*(.|\n)*@@} 

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

Any help appreciated.
