As a general principle, don't use xsl:for-each for processing stuff you want
handled in document order. Keep it for stuff you want to sort, or stuff
that needs handling out of order. Just use templates for normal processing.

If you really just want to output absolute subsets of the markup (ie not
changing anything about each entry), all you need is:

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="/">
    <collection>
      <xsl:copy-of select="collection/cd[contains(artist,'The Beatles') 
                           and year='1966']"/>
    </collection>
  </xsl:template>
  
</xsl:stylesheet>
