XQuery and the power of learning by example
If you set out to explore XQuery, the XML query language, you’ll soon encounter a collection of examples, or use-cases, that show how XQuery can query and transform XML data. These scenarios are elaborated in a W3C document that presents a sample data set — about books, authors, prices, and reviews — and enumerates a set of queries against that data. For each query, there’s a description (“List names of users who have placed multiple bids of at least $100 each”), a solution written in XQuery code, and an expected XML output.
