Chapter 16. xTract: A Query-By-Example XML Retrieval System
In this chapter, we develop xTract—a utility for retrieving fragments of XML files matching particular search criteria on the Web.
The user specifies a search template in a manner similar to Query-By-Example systems often used with relational databases.
An example will help make this clear. The web site http://www.slashdot.org publishes an XML file on their site that lists the main stories of the day. The geturl utility developed earlier can be used to retrieve this file.
