Hello,

actually the problem is the mess SIMPLE RFC authors made with XML namespaces, by not setting and not using a prefix for them, otherwise the #012 is end-of-line printed by syslog as octal character.

The solutions:

1) replace "xmlns=" with something else like "xyzwq=":

$xml(body=>doc) = $(rb{s.replace,xmlns=,xyzwq=})

and use xpath without concerning of xml namespaces prefix.

2) register a prefix for the namespace using xml_ns parameter from xmlops module and use that prefix in xpath expressions.

See a past discussion on the mailing list:

Cheers,
Daniel

Hello

Just to add, when I'm trying to dump $rb to logs, I'm getting this line

<?xml version="1.0"?>#012<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="0" state="full" entity="sip:88881@dev.company">#012  <dialog id="f-XGMVyeO0" direction="recipient">#012    <state>terminated</state>#012  </dialog>#012</dialog-info>

So, I expect problem is in this #012 + extra spaces. Is there a way to clean it up in an easy way?

Regards,
Igor

Hello,

I'm trying to get state of endpoint from PUBLISH message in a most simple way using xmlops module

Trying to make this

$xml(body=>doc) = $rb;
log("L_ERR", "$rU is now in state $xml(body=>xpath:/dialog-info/dialog/state)\n");

XML in PUBLISH itself

<?xml version="1.0"?>
<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="0" state="full" entity="sip:88881@dev.company">
  <dialog id="v6qmEYf5yI" direction="initiator">
    <state>confirmed</state>
  </dialog>
</dialog-info>

Actual text in log is

... <script>: 88881 is now in state

Means it's empty. xmlops module is loaded with no parameters. Tried also string

$xml(body=>xpath:/dialog-info/dialog/state/text())

-> same result

What am I missing here?
