XML to XML transformation

[yashc]

Hello,

<rentalProperties>
    <property available="yes" contact="0455 455 014">
        <type>apartment</type>
        <price>500</price>
    <address>
        <streetNo>15</streetNo>
        <street>Armadale Street</street>
        <suburb>Armadale</suburb>
        <state>VIC</state>
        <ZipCode>3143</ZipCode>
    </address>
    <numberofBedrooms>2</numberofBedrooms>
    <numberofBathrooms>1</numberofBathrooms>
    <garage>1</garage>
    <description>Top floor 2 bed Apartment in a Leafy Street with 2 carspaces</description>
    </property>
</rentalProperty>

I have to transform this into xml format using xslt. The address should be separated by comma, and zipcode shouldnt be included.
Can you help me out?
