Xpath query to get the parent Element text and its child element attribute values?

Question

I have the following XML :

<sample>
  <Message number="2">
  <Title>Program pointer has been reset</Title> 
  <Description>
  The program pointer of task 
  <arg format="%s" ordinal="3" /> 
  has been reset. 
  </Description>
  </Message>
</sample>

I'm trying to get the decription text with arg attribute values. Something like "The program pointer of task %s 3 has been reset."

and my attempt looked something like

'/sample//Message[@number = $mId]/Description'

but that didnt work.

With XPath 2.0 or XQuery 1.0 you could use string-join(/sample//Message[@number = 2]/Description/(text() | */@*), '') . I am not sure whether Python gives you access to an XPath 2.0 or XQuery 1.0 library.
