  xsl:value-of only returns the string version of the first match.  You 
would need the xsl:for-each in order to get all of them.  Try something 
like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:template match="/">
    <xsl:for-each select="//@width/..">
      <xsl:value-of select="."/><br/>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

  The selection is not the problem, the value-of is.  The selection indeed 
selected all of the nodes (though your version of /rooms/room[@width] is 
faster).  The value-of only grabbed the first one.
