Welcome to the Query Portal, which is one of the main sections of the documentation. Here your find more information on performing XPath and XQuery requests. Apart from standard features, BaseX offers numerous extensions, which are listed on this page.
Extensions
- Full Text: full-text features of XQuery
- Update: update mechanism of XQuery
- Java Bindings: how to call Java methods from XQuery
- XQuery 3.0: supported features of the upcoming W3C XQuery 3.0 Recommendation
Functions
- Database (db): Database-related functions
- Full Text (ft): Full-text functions
- Utility Functions (util): Testing and profiling functions
- Math Functions (math): functions for mathematical operations
- File Functions (file): functions for file handling, inspired by the EXPath File Module
- HTTP Functions (http): Full-text functions, based on the EXPath HTTP Client Module
A complete list of the standard XQuery 3.0 functions is found in the Official W3C Specification.
Indexes
Queries will be analyzed and optimized for index access on the fly.
- Overview: All indexes and their functionality
- Execution Plan: Execution plans of the queries
