Converting RSSTV XML with XSLT

I am trying to transform RSSTV XML using XSLT.The problem I am having is that I need the XML to look like this:<?xml version="1.0"?><rss xmlns:tv="http://www.rss-tv.org/rss/tv1.0" version="2.0"><channel>

However, I am unable to create the rss element with this attribute.I tried using <xsl:attribute> but failed to achieve it.
