attributes of a parent node

Hello everyone,
Is it possible to get to an attribute of a parent node?

Example XML:
<question number="1">What is your phone number?
	<subquestion number="1">Home phone number?</subquestion>
	<subquestion number="2">Work phone number?<subquestion>
</question>
<question number="2">What is you name?
	<subquestion number="1">First name?</subquestion>
	<subquestion number="2">Last name?</subquestion>
</question>

I want to get an output of:

1. What is your phone number?
	1.1 Home phone number?
	1.2 Work phone number?
2. What is your name?
	2.1 First name?
	2.2 Last name?

In the example I want to get to the number attribute of the question while
working within a subquestion.
How can this be done?

Thank you in advance,
Christina Vlattas
