菜鸟求助！怎么用javascript读取这样的数组？

[TomSweet]

xml version="1.0" encoding="gb2312" standalone="yes" ?>
<X3D>
  <Scene>
    <!--Scene graph nodes are added here -->
    <Shape bboxSize="-1 -1 -1">
        <!--Add Appearance and a single geometry node here-->
        <Appearance>
            <!--Add Material, Texture, TextureTransform, FillProperties, and/or LineProperties nodes here-->
            <Material diffuseColor="1 0 0"/>
        </Appearance>
        <Cone bottomRadius="2" height="3"/>
    </Shape>
  </Scene>
</X3D>

我想改变Material里的diffuseColor为别的颜色，比如0 0 1，请问怎么改啊？

参考js 读取xml文件的示例

涉及浏览器兼容

new ActiveXObject('MSXML2.DOMDocument')
new ActiveXObject('Microsoft.XmlDom')
