The applet on this page contains a parser for the language defined by XQuery 1.0: An XML Query Language with XQuery and XPath Full Text 1.0 [2010-01-28 CR]. It allows you to type in an expression, and then view the parse tree, or else obtain an error if it is syntactically incorrect. The results should not be used as an absolute reference, and may flag legal syntax or errors not intended by the drafts. However, the parser used here was generated by processing the same representation of the grammar that was used to produce the EBNF productions in the corresponding specification(s). This parser is also used by the working groups to validate the integrity of the grammar.
This page is meant to be a tool for readers and parser implementers. Implementers are invited to visit the Resources section below the applet.
Type in a XQuery 1.0 with Full Text expression then click on the button:
