F5 iRule to get data group address content values list

I managed to remove the brackets by simply getting the values. iRule looks like this now:

when HTTP_REQUEST {
    HTTP::version 1.0
    HTTP::header remove Accept-Encoding
    switch -glob [string tolower [HTTP::uri]] {
    "/azure.html" {
       # Retrieve the Azure datagroup contents, send it in a HTTP 200 response
	   HTTP::respond 200 content [class names azure_ipv4_dg] "Content-Type" "text/html"
       }
    }
}

It now gives me something like this:

102.133.0.0/18 102.133.112.0/28 102.133.120.0/21 102.133.128.0/18 102.133.192.0/19 102.133.224.0/20 102.133.240.0/25 102.133.240.128/26 102.133.248.0/21 102.133.64.0/19 102.133.96.0/20 102.37.0.0/20 102.37.128.0/19 102.37.16.0/21 102.37.160.0/21 102.37.192.0/18 102.37.24.0/23 102.37.26.0/27 102.37.26.32/27 102.37.32.0/19 102.37.64.0/21 102.37.72.0/21 102.37.80.0/21 102.37.96.0/19

So the only thing I need is to replace space with line breaks. Any ideas?
