xf:idref(string* $srcval) => node* 11.7.2.3 Semantics Returns the sequence of element nodes with an IDREF value matching the value of one of the items in the sequence argument or an IDREFS value containing an IDREF matching the value of one of the items in the sequence argument. If the value of $srcval is a single string, it behaves as though a sequence of length one of strings was supplied. This function allows reverse navigation from IDs to IDREFs. Thanks Jeni. Do you read this as working in this case? The last sentance appears to imply singular? Guessing that the sequence argument is the param to the function, this would appear to get all IDREF type 'pointers' to this id, I'm unsure if it would resolve <xf:for-each select = xf:idref ($this-node-id)> where the 'pointers' were buried in the midst of an IDREFS type string. <a idrefs=" x y z"/> <b idrefs=" m n z"/> <z id="z"/> <template match="z" <xf:for-each select = xf:idref (@id)> </xf:for-each> Do you think this would find both a and b element nodes? (assuming proper dtd definitions of id and idrefs) > Another approach would be to use a tokenize() extension function to > get the values against which the processes were keyed.

I'd not thought outside the box on this one.
