    <fruits>
        <fruit>
            <name>apple</name>
            <color>red</color>
        </fruit>
        <fruit>
            <name>banana</name>
            <color>yellow</color>
        </fruit>
        <fruit>
            <name>blackberry</name>
            <color>purple</color>
        </fruit>
        <fruit>
            <name>blueberry</name>
            <color>blue</color>
        </fruit>
        <fruit>
            <name>orange</name>
