All Implemented Interfaces:
Function
public class NormalizeSpaceFunction extends Object implements Function

4.2 string normalize-space(string)

The normalize-space function returns the argument string with whitespace normalized by stripping leading and trailing whitespace and replacing sequences of whitespace characters by a single space. Whitespace characters are the same as those allowed by the S production in XML. If the argument is omitted, it defaults to the context node converted to a string, in other words the string-value of the context node.
