Introduction
XQuery is a powerful language used for querying and transforming XML data. If you're interested in learning the basics, here are some key concepts to get you started: 1. Basic Syntax XQuery is case-sensitive. Use let, for, where, and return to construct queries. 2. Selecting Nodes Use the // operator to select nodes from anywhere in the XML document. Use . to refer to the current node. 3. Functions Built-in functions like count(), string(), and substring() are commonly used. 4. Filtering Use where to filter results based on conditions. 5. Combining Data Use union to combine results from different queries. Example Query Here’s a simple example to select all book titles from an XML document: xquery Copy for $book in //book return $book/title Learning Resources Official Documentation: Check out the W3C's XQuery specifications.
