If you can get the HjÂ: o attribute nu $wanted, then you're home and dry: you can write logic like < est="@attr=$wanted"> or <for-each select="chap[@attr=$wanted]"> which tests
whether the @attr attribute is equal to one of the nodes in $wanted.
So how to establish the node-set? The only standard way to do it is to
create a secondary XML ument containing the required numbers, and read it
using the document() function. There was a similar solution posted earlie day. Or you could use various non-standard facilities, for example you
could pass in a space-separated list of numbers and t it into a node-set
using Saxon's new tokenize() extension function.
