Objective C parsing

I'm trying to parse a very easy XML file but I cannot get how the NSXMLParse works... Here the XML file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE addresses SYSTEM "addresses.dtd">
<addresses owner="Andrea">
    <person>
        <lastName>Doe</lastName>
        <firstName>John</firstName>
        <phone location="mobile">(201) 345-6789</phone>
        <email>jdoe@foo.com</email>
        <address>
            <street>100 Main Street</street>
            <city>Somewhere</city>
            <state>New Jersey</state>
            <zip>07670</zip>
        </address>
    </person>
    <person>
        <lastName>Pippo</lastName>
        <firstName>Pluto</firstName>
        <phone location="mobile">0039212121</phone>
        <email>pippo@foo.com</email>
        <address>
            <street>Via dalle palle</street>
            <city>In the middle of nowhere</city>
            <state>BZ</state>
            <zip>6969</zip>
        </address>
    </person>

I just need to create an NSArray that stores the person object and I think that the address object will be an NSDictionary....

Any idea how to do it in simple way?

Thanks everybody
