Welcome to the Query Portal, which is one of the [[Main Page|mainMain Sections]] sections of this documentation. Here you can find more information on performing BaseX provides an implementation of the W3 [http://www.w3.org/TR/xpath-30/ XPath ] and [http://www.w3.org/TR/xquery-30 XQuery requests] languages, which are tightly coupled with the underlying database store. Apart from standard featuresHowever, BaseX offers numerous extensionsthe processor is also a flexible general purpose processor, which are listed can access local and remote sources. High conformance with the official specifications is one of our main objectives, as the results of the [http://dev.w3.org/2006/xquery-test-suite/PublicPagesStagingArea/XQTSReportSimple_XQTS_1_0_2.html XQuery Test Suite] demonstrate. This section contains information on this page.the query processor and its extensions:
