not to be a url pusher .....

in general this will say,
a) find all <autor> elements and put the resulant tree in a variable,
with a filter getting rid of duplicates ( something like the following )
<xsl:variable name="uniquelist" select="//autor[not(.=following::autor)]"/>
you may have a problem with some parsers, most recent version of
sablotron has a problem with these types of xpaths.
