Send a variable to flash via html-code

How can I with the html-code include a variable that you can take out in flash?

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="481" height="332" id="denstora" align="middle">
<param name="allowScriptAccess" value="sameDomain" />
<param name="movie" value="denstora.swf" />
<param name="quality" value="high" />
<param name="bgcolor" value="#ffffff" />
<embed src="denstora.swf" quality="high" bgcolor="#ffffff" width="481" height="332" name="denstora" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
</object>

Also, just a little variable. (xmlfile=text.xml) (I want to have the same swf-file but use it in several html-files (and I have one xml-file to every html-file))
