Michael: I don't think that I overlooked using position() within template, as triggered in the apply-templates mode. But as position() is context-dependent, it will not return the same value as when applied within a for-each over a summarily constructed sequence of nodes. The requirement is (cf. that other thread started yesterday) to enumerate certain nodes across the entire document. -W On 4 November 2014 12:49, Michael Kay mike@xxxxxxxxxxxx < xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> wrote: > Are you missing the fact that position() can be used during > apply-templates processing, in the same way as during for-each processing? > > Michael Kay > Saxonica > mike@xxxxxxxxxxxx > +44 (0) 118 946 5893 > > > > > On 4 Nov 2014, at 11:28, Wolfgang Laun wolfgang.laun@xxxxxxxxx < > xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> wrote: > > A recent post has asked for a way to produce ordinals for the processing > of a set of certain nodes. > > If you construct a sequence of the required nodes and iterate it (using > for-each), position() yields the ordinals. > > If you use template/apply-templates. you can still determine the offset by > calling index-of.
