[xsl] XPath/XSLT 2.0: What is the most efficient way to find if a sequence is empty?
Subject: [xsl] XPath/XSLT 2.0: What is the most efficient way to find if a sequence is empty? From: "Dimitre Novatchev" <dnovatchev@xxxxxxxxx> Date: Sat, 4 Oct 2003 22:59:33 +0200 |
In XSLT/XPath 1.0 one would use: not($node-set) to find if $node-set is the empty node-set. However, the same test on a sequence in XPath 2.0: not($seq) may return 'true' for a non-empty sequence -- e.g. for: ( false() ) or for (0) My question: Is there a more efficient test for an empty sequence than count($seq) = 0 ===== Cheers, Dimitre Novatchev. http://fxsl.sourceforge.net/ -- the home of FXSL XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
