Daniel,

Many thanks!

Your "replace" solution looks more elegant than just remove the whole string.

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?

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?
