All Implemented Interfaces:

Callable, FunctionItem, GroundedValue, Item, Sequence

public class UnescapeNCName
extends SystemFunction

The saxon:unescape-NCName function reverses the effect of saxon:escape-NCName: it takes an NCName constructed using saxon:escape-NCName as input, and returns the string from which it was constructed. A dynamic error is raised if the input contains an invalid escape sequence.

call

public StringValue call(XPathContext context,
                        Sequence[] arguments)
                 throws XPathException

context - The XPath dynamic evaluation context. Not used in this case

arguments - The values of the arguments to the function call.

Returns:

The unescaped NCName

Throws:

XPathException - if lazy evaluation of the supplied argument fails, or if the input contains an invalid escape sequence
