Link’s Target and FrameSet?

Hi,
Is there any way to make a control on any html page may be available in the frameset to make its links to be opened in this frame, regardless its own link target.
for example,
suppose I create a frame set, in one of its frames the yahoo home page will be loaded, and suppose yahoo’s web master made all link’s target to be blank. Now I want any link on the yahoo page in my frame to be opened in the same frame.

<frameset>
<frame src=”mypage.html” name=”head”>
<frame src=”http://www.yahoo.com” name=”body”>
</frameset>
