Re: keys and idrefs - XSLT2 request?
Hi Dave, > Which as you point out, indicates that XSLT has no means of using > keys (simply) on idrefs, to find 'reverse' links. > > I don't particularly like the use of string routines in attributes > to achieve this, I wonder if this drives an XSLT 2 request? See http://www.w3.org/TR/xquery-operators/#b2b7b4c22c26c14, which as you might guess from the anchor (!) is a description of xf:idref() to do just what you're after, enacting the requirement 2.12 of the XSLT 2.0 Requirements. Another approach would be to use a tokenize() extension function to get the values against which the processes were keyed. This would work because when a node has a node set as a key value it is indexed by the values of all the nodes in the node set. So you could do something like: <xsl:key name="control" match="process" use="str:tokenize(@control)"/> And of course this would work whether you had access to the DTD or not.
