Welcome to the Query Portal, which is one of the Main Sections of this documentation. BaseX provides an implementation of the W3 XPath and XQuery languages, which are tightly coupled with the underlying database store. However, the processor is also a flexible general purpose processor, which can access local and remote sources. High conformance with the official specifications is one of our main objectives, as the results of the XQuery Test Suite demonstrate. This section contains information on the query processor and its extensions:

Features of the upcoming XQuery 3.0 Recommendation.

Additional function modules provided by BaseX.

Embedding of external modules, based on the EXPath Packaging System.

Accessing and calling Java code from XQuery.

 

How to use BaeX as a full-fledged full text processor.

Updating databases and local resources via XQuery Update.

Serialization parameters supported by BaseX.

Errors raised by XQuery expressions.
