Mapping of XML / random

[psiotwo]

I am trying to map an XML nested list (full example attached):

<person>
   <identifier>1</identifier>
   <address>
       <type>email</type>
       <value>a@b.com</value>
   </address>
   <address>
       <type>phone</type>
       <value>+12345</value>
   </address>
       ...

to produce RDF of the form

:person-1 :hasAddress :address-2 .
:address-1 :type "email" .
:address-1 :value "a@b.com" .
:address-2 :type "phone" .
:address-2 :value "+12345" .
...

Addresses don't have any natural well defined identifier (the value/type fields are noisy) so some artificial needs to be crafted. I don't care about their form, so I tried:

• to automatically generated it using idlab:random, but it does not seem to work because RMLStreamer seems to generate the random ID for each address multiple times - which seems to make it disconnected from the person (as in the attachment)

• to be derived from the location of the element in XML using some XPath expression.

Neither worked.

Is there any other option to map that XML to RDF in the way suggested?
