Multiple attributes / extraction of a specific value with unlang regex ?
Hello, I'm working with FreeRADIUS 3.0.1. I'm trying to extract a value from an array of attributes, such as : Cisco-AVPair = "<prefix>=<value>" There are multiple Cisco-AVPair values in packet, I want to extract <value> from the attribute starting with "<prefix>=". I read this from unlang man page : %{Attribute-Name[*]} Expands to a single string, with the value of each array member separated by a newline. (note that it seems members are separated by ",", not by a newline) So I tried the following : if ("%{Cisco-AVPair[*]}" =~ /circuit-id-tag=([^,]*)/ ) { update control { My-Cisco-Circuit-Id := "%{1}" } } This works, but is not good enough because <value> might contain a comma. Is there a better way to do this with unlang ? Thanks. This message contains information that may be privileged or confidential and is the property of the Capgemini Group.

As Arran has said, foreach: foreach (Cisco-AVPair) { if (Foreach-Variable-0 =~ /^circuit-id=(.+)/) { update control { My-Cisco-Circuit-Id := "%{1}" } } } At one point I submitted a patch to make the regexp operator logic loop through all matching values, but I think this functionality went away when unlang was rewritten.
That's perfect, thanks a lot! And it was described in unlang man, I missed it... my bad. Sorry :/
