Issues modifying XML content with stream profile & iRule

Alright, problem solved. I finally got the escaped characters in the XML files to match and substitute like I wanted. Hopefully this helps someone else.

 when RULE_INIT {
    set static::search "http:\\\\\\\/\\\\\\\/oldapplicationdomain"
    set static::replace "https:\\\/\\\/newapplicationdomain"
}

when HTTP_REQUEST {

     Disable the stream filter for all requests
        STREAM::disable

       HTTP::header remove "Accept-Encoding"
}

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

   Replace http:// with https://
   STREAM::expression @${static::search}@${static::replace}@ 

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

    }
}
