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

<customers>
<customer id="7" phone="555-555-1211">
<name firstName = "Thomas" lastName = "Jensen"/>
<address street="12 Willow Way" city="Treeland" state="NJ" zip="14322" />
</customer>
<customer id="8" phone="555-555-1213">
<name firstName = "Henrick" lastName = "Jensen"/>
<address street="12 Willow Way" city="Treeland" state="NJ" zip="14322" />
</customer>
</customers>

You need to use XPATH retrieve the customer element with the id 8.
Which code segment do you use?
