  Probably not very clear in my first email, but
you can change the xml
 content:

 $xml(a=>xpath:/presence/mynode) = "123"; 
 When reading, which is the result if the node doesn't exist? empty 
 string?
 If a=>xpath:/presence/mynode gets 123 (an integer) can it be used in 
 math operation as integer? or is it a string?

  Note that if you assigned the sip message body to
$xml(name=>doc), body
 does not get changed, the operations are done on a replica. 
 So modifications in the body must be done in the proxy before 
 forwarding the request to the presence server, or doing a spiral if 
 the presence server is integrated in the proxy, right? 
 Hi Daniel!

 In sip-router there is functionality to apply lumps before sending (it 
 is used for SIP-Identity). Maybe this could be exported to script and 
 can be executed manually to triggering reconstruction of the message, 
 e.g. for processing the modified message in the presence module. it does not work
now directly on msg body, but your approach can get 
life using set_body() from textops.

Applying lumps would be good to add as experimental function in config, 
to see how much it affects the rest.

Cheers,
Daniel
