Functions, operators, and data types for XPath 3.0
The current state of implementation of all standard functions is now documented here.
The new function
The higher-order functions
are implemented - note that these are in the namespace
http://www.w3.org/2005/xpath-functions/math. Unlike the other new functions, these are available whenever
Saxon-PE or Saxon-EE are in use, regardless of whether XQuery 3.0 or XPath 3.0 are enabled - this is conformant because
they are in a namespace to which the 1.0/2.0 specifications attach no restrictions.
The single-argument version of
The two-argument version of
The zero-argument forms of
function is implemented.
The new regular expression flag "q" is recognized. This causes all characters in the regex to be treated as ordinary characters, for example "." will match a single period, rather than matching any character. This is only recognized when XPath 3.0 or XQuery 3.0 is enabled.
Non-capturing groups are recognized, with the syntax
(?:aaaa) where aaaa is any regular expression.
