You are creating an application that performs contact management. You load customer information from the following XML to an XmlDocument object named doc:

<customers>
<customer class="primary" phone="555-555-1211">
<pcp id="2432" />
<name firstName = "Thomas" lastName = "Jensen"/>
<address street="12 Willow Way" city="Treeland" state="NJ" zip="14322" />
</customer>
<customer class="primary" phone="555-555-1213">
<pcp id="2433" />
<name firstName = "Henrick" lastName = "Jensen"/>
<address street="12 Willow Way" city="Treeland" state="NJ" zip="14322" />
</customer>
</customers>

You need to retrieve the city of the first customer.

Which code segment do you use?
