Selenium 未找到SVG元素

我使用selenium RC的

getAttribute

方法来获取SVG元素的颜色。 HTML代码如下所示：

<div style="width: 600px; height: 350px;">
<svg overflow="hidden" width="600" height="350">
<defs/><circle fill="#F0F8F8" fill-opacity="1.0" stroke="black" stroke-opacity="1.0" stroke-width="1" r="120" cx="300" cy="175"/><circle fill="#00bb00" fill-opacity="1.0" stroke="black" stroke-opacity="1.0" stroke-width="1" r="30" cx="420" cy="175"/>
</svg></div>

错误：
