Subject: Re: [xsl] [XPath 1.0] Why is .[A] illegal but self::node()[A] is legal? From: Wolfgang Laun <wolfgang.laun@xxxxxxxxx> Date: Sat, 7 Aug 2010 18:05:59 +0200 |
According to the syntax in "XML Path Language (XPath) Version 1.0" (http://www.w3.org/TR/xpath), a <Step> is either the sequence <AxisSpecifier> <NodeTest> <Predicate>* OR an <AbbreviatedStep>. The latter may expand to a '.', therefore, no predicate after '.' With self:: node() [A] you follow the first alternative of the <Step> NT. -W On 7 August 2010 17:17, Costello, Roger L. <costello@xxxxxxxxx> wrote: > > Hi Folks, > > Why is this XPath 1.0 expression illegal: > > .[A] > > whereas this XPath 1.0 expression is legal: > > self::node()[A] > > > Isn't '.' a shorthand for 'self::node()'?
