Hi Richard, I cannot say anything definite about which expressions are optimal, my only remark is that the following too are completely different -- it is an error to assume they are equivalent in case x and y are node-sets: not(x=y) x!=y Dimitre Novatchev. ------------------- Original Message ------------------ To: XSL-List at mulberrytech dot com Subject: Performance versus legibility From: "Richard Birkby" <rbirkby at hotmail dot com> Date: Fri, 24 Nov 2000 14:16:32 -0000 Reply-To: xsl-list at mulberrytech dot com -------------------------------------------------------------------------------- not(string(.)) string-length(.)=0 not(x) count(x)=0 not(x=y) x!=y I always use the expressions in the second column for maintainability, but I guess the items in the first column are faster. Is my assumption correct? Are there any other performance bottlenecks in common usage? Richard __________________________________________________ Do You Yahoo!? Yahoo! Shopping - Thousands of Stores.
