xpath of an Embedded html in Iframe

[Arun Kumar C C]

I have a similar issue posted in ;

https://groups.google.com/forum/#!topic/firebug/8WxWiX2k9A8

"When you inspect a page that uses iframes to display other webpages
and try to get an inner element (within in the embedded page) this
doesn't work.

Instead, when you get to the point /html/body/..../iframe  the
following  XPath information again starts with /html/body/...because
from that point it only regards the embedded page, not the surrounding
one any more.

Is this intended behaviour or a bug?"

Can someone please advice on a solution?

I am using Selenium Webdriver and i am not able to click on that inner element, since i don't have xpath to do that.
