[Webtest] How to locate a element without name ,Id,HtmlId and a Japanese lable.

[lostinheaven . lee]

Hi Everyone,I'm practicing webtest on an Japanese project. in that project
which many buttons are without of neither Id nor name, all of the label is
written in Japanese,so I can't use Xpath to located them neither.

How can I specify an element without those parameter? Or I have tohad some
of those parameter added?

Thanks!
