XML with Recursive Querying
Kamal Taha, Ramez A. Elmasri · 2009
We introduce an XML search engine called XRQ. The search engine employs recursive querying techniques for answering XML loosely structured queries. Recursive querying allows a query to query the results of a previous application of itself or of another query. We experimentally evaluated the search quality and efficiency of XRQ and compared it with two search engines, XSeek and XKSearch.
