Search is specific to the medium at hand. So, yes, it would be appropriate
to search the _rendered_ text, however it might be rendered. For example,
for PDF output, a PDF reader's search function could be quite different from
Info's. Likewise, for XHTML, a browser's search could be different from

I doubt there would be much call for searching the underlying XML, but, if
there were, then XQuery or XPath expressions would be appropriate. I see no
sense in trying to regexp search across XML nodes, with the possible
exception of searching only the text() nodes (as you mentioned).
