The XML (eXtensible Markup Language) is a common format used to

structure and store data on the web. The following is a small sample XML

file that could be used to store names in an address book. Type it in using

a text editor and save it to a file named address.xml (or find it on the

accompanying CD). (continued)

<?xml version="1.0"?>

</address_book>

The sample file contains four contacts. The <> tag denotes the start of a

field and the </> tag denotes the end of the field.

a) You are hosting a party in Palmdale, CA. Write a program that reads in

the address.xml file and outputs the names and addresses of everyone

in Palmdale. Your program shouldn’t output any of the tag information,

just the address content.

b) You would like to send an advertising flyer to everyone in zip codes

90210 through 90214. Write a program that reads in the address.xml

file and outputs the names and addresses of everyone whose zip code

falls within the specified range.

You may assume that each contact in the address file has the same

structure and the same fields. However, your solution should be able to

handle an input file with any number of contacts and should not assume

that the fields within each contact are in the same order.
