Get values from an XML file

Hello list,

I'm having problem parsing an XML file with JavaScript. I've
looked through all the books I have and plenty of google
searches but I keep hitting brick walls. Here's the
structure of my XML file:

<rootNode>
    <mainItem>
        <widgetName>Sprocket</widgetName>
        <property1>Foo</property1>
        <property2>Bar</property2>
    </mainItem>
    <mainItem>
        <widgetName>Cog</widgetName>
       <property1>Hello</property1>
        <property2>World</property2>
    </mainItem>
</rootNode>


So I can get the XML file into a variable just fine:

    var doc = request.responseXML

And I can even get the <mainItem>s into a variable
too:

    var items = doc.getElementsByTagName('mainItem')

But from here I'm stuck. Using firstChild, hasChildNodes(),
or anything of the like gets me stuck. Can anyone shed some
light or point me in the right direction? I'm trying to get
down into the values of the mainItem properties (e.g. output
"Sprocket", "Foo", "Bar",
etc)

Thanks
-Nick
