Re: [xsl] Detecting presence of attributes

[Dimitre Novatchev <dnovatchev at yahoo dot com>]

Hi Peter,

In case the value was not a list of entity names, but of type IDREFS,
then the id() function will return a nodeset of nodes that have one of
the id-s in the list as the value of their ID attribute.

Then you could iterate on these ID values -- fortunately, only the
first node having a particular @ID value will be returned (as stated in
Mike Kay's book).

Therefore, the XPath expression you might find useful would be:

id(@foo)/@ID

However, it seems to me that this is not exactly your case. In any case
the list of names can be processed recursively.  

In Saxon there's saxon:tokenize().
