Subject: [xsl] Which is faster: count(/Document/A/B) eq 1 ... or ... /Document/A/(count(B) eq 1) ? From: "Costello, Roger L." <costello@xxxxxxxxx> Date: Wed, 19 Sep 2012 13:34:19 +0000 |
Hi Folks, Consider this XML document: <Document> <A> <B>blah</B> </A> </Document> Here are two XPath expressions to test that there is exactly one <B> element in the <A> element (assume there is only one <A> element): 1. count(/Document/A/B) eq 1 2. /Document/A/(count(B) eq 1) Which is faster? Is there an XPath expression, besides the ones listed, that is even better and faster? /Roger
