Subject: RE: [xsl] [XPath 2.0] Two XPath expressions to the same node, yielding different results with "instance of text()" From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Wed, 7 Oct 2009 22:09:23 +0100 |

Probably because the first expression selects the singleton text child of a single MembershipFee element, whereas the second expression selects the children of every MembershipFee element that is the first child of its parent. Try "instance of text()*" to verify this. //X[1] is a common error when (//X)[1] is intended. Or it may be better to write /descendant::X[1] for clarity.
