Re: extract the right elements

> <xsl:for-each select="//INSTANCE[@class='Audio' or @class='Web-Site']">
This loops over the nodes that you want but then having got there you do this:  

>   <xsl:for-each select="key('tracker','Position')">

which selects all the nodes  using the constant key 'Position' so it
does not depend in any way on the INSTANCE node and so the inner loop
will produce identical <item> elements one for each of the originally
selected  INSTANCE[@class='Audio' or @class='Web-Site' elements.

insde this for-each the current node is whatever node is returned by
your key, so your INSTANCE elements are not used at all.
