Pure XPath alone (at least in versions 1.0 and 2.0) does not provide any 
features to sort. However languages like XQuery or XSLT which make use 
of XPath provide features to sort, XQuery with the order by clause in 
FLWOR expressions (http://www.w3.org/TR/xquery/#id-orderby-return) and 
XSLT with the xsl:sort element (http://www.w3.org/TR/xslt20/#xsl-sort) 
and XSLT 2.0 additionally with xsl:perform-sort 
(http://www.w3.org/TR/xslt20/#creating-sorted-sequence).

Depending on the XPath API you use there might also be sorting features 
exposed for instance in .NET's XPath's API you can use
