Quick XML Access Question

I’m new to working with xml and was wonder how I would access the <otherthumbs> node and get the data from the<image> node.

Here is an example of the xml:

<images>
    <pic>
        <category>Bodysuit</category>
        <name>Body Suit 1</name>
        <description>Body Suit 1 description.</description>
        <mainimage>photos/bodysuit/large/bs1.jpg</mainimage>
        <mainthumb>photos/bodysuit/small/bs1.jpg</mainthumb>
        <price>$00.00</price>
        <sizes>0 - 0</sizes>
        <otherimages>photos/bodysuit/large/bs1.jpg</otherimages>
        <otherthumbs>
            <images>photos/bodysuit/small/bs1.jpg</images>
            <images>photos/bodysuit/small/bs2.jpg</images>
        </otherthumbs>
    </pic>
</images>

Here is the ActionScript I have so far:

xmlNode = this.firstChild;

for (r=0; r<other_total; r++) {
otherthumbs[r] = xmlNode.childNodes*.childNodes[8].childNodes[r].firstChild.firstChild.nodeValue;
}

If anyone could help it would be great!

Thanks.
