Currently, to my knowledge, there are no search enginces or plug-ins which
will search within an XML document to, say, extract the material falling
within tag "x", or all authors (<author></author>) named James
(<author>James</author>), thus use of the XML tagged data identification
in a text-based data resource (e.g., academic article, etc.) can only be
selectively displayed through multiple style sheets (cf. MS IE5beta
presentation at GCA '98).

If I am incorrect, please let me know of such a search engine.  Otherwise,
I am curious if anyone else has encountered this query/rendering
tag-exploitation issue.
