v5.0.4: Transformation param.value,name: Returning incorrect result

[00Asgaroth00]

Description

Given the following Path header:

Path: <sip:10.7.0.186:5062;lr;received=sip:212.2.172.228:39808>

When logging with the following log line

xlog("L_INFO", "received_address: '$(hdr(Path){param.value,received})'");

I am seeing the following being logged in the logs:

INFO: <script>: received_address: 'sip:212.2.172.228:39808>'

Notice the trailing angle bracket (>).

I would have expected it to return something like the following:

'sip:212.2.172.228:39808'

Am I using this transformation correctly, or is this indeed a small bug?

Path header value is not a sip parameters string (which is name1=value1;name2=value2; ...), but a name-address. You are using the wrong approach by doing only param transformation. Sometimes you may get the right value (eg., in this case, when there is another parameter after received), but that's because of a pure string delimiter parsing.

So, you have to combine {tobody.uri} and {param.value,received}

Thanks for the correct usage explanation, sorry for the noise on the issue tracker.
