Subject: Re: [xsl] // expanding to descendant-or-self::node() From: David Carlisle <davidc@xxxxxxxxx> Date: Tue, 16 Sep 2008 14:37:13 +0100 |
a slightly more serious answer than my frivolous first reply... currently // expands to /descendant-or-self::node()/ which is not owhat one would first think of, but it works consistently without depending on the following step. And that expansion is at the level of expression terms not syntax fragments. one might expect // to expand to descendant:: but descendant:: itself isn't really an expression, just part of the syntax for an axis step and that causes problems.. //foo could have been defined to be /descendant::foo but you can not define //@foo to be descendant::@foo as that's a syntax error, wheras /descendant-or-self::node()/@foo is all foo attributes in the document, which is the desired meaning. similarly any other axis, including child:: //child::foo can't expand to /descendant::child::foo David ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
