org.pdf4j.saxon.query.StaticQueryContext.compileQuery()
Prepare an XQuery query for subsequent evaluation. The source text of the query is supplied as a String. The base URI of the query is taken from the static context, and defaults to the current working directory.
Note that this interface makes the caller responsible for decoding the query and presenting it as a string of characters. This means it is likely that any encoding specified in the query prolog will be ignored.
@param query The XQuery query to be evaluated, supplied as a string. @return an XQueryExpression object representing the prepared expression @throws org.pdf4j.saxon.trans.XPathException if the syntax of the expression is wrong, or if it references namespaces, variables, or functions that have not been declared, or contains other static errors. @since 8.4
