Well
   tbody/row/entry[1]
potentially selects several 'entry' elements. It all depends on how you 
use that XPath. In XSLT 1.0 if you do e.g.
   <xsl:value-of select="tbody/row/entry[1]"/>
then the string value of the first 'entry' element in the node-set is 
output. With XSLT 2.0 that is different.

And XSLT/XPath 2.0 have a lot more expressive power for instance you can 
use e.g.
   <xsl:if test="every $e in tbody/row/entry[1] satisfies 
not(normalize-space($e))">

XSLT/XPath 2.0 is implemented by Saxon 9 from 
http://saxon.sourceforge.net/ and AltovaXML tools from 
http://www.altova.com/.
