How to insert tag to a feed rss

[Antony]

For example i want to insert
<%block_rss_feed url="http://news.google.com/news?q=<%$tag%>&output=rss" title="Hotel Discount News Travel" template="block.rss_feed.html" max_item="3" cache_time="6400"%>
But that doesn't work.
Somebody knows how to do it ?

[Antony]
