Normalization of whitespace characters in a string with normalize-space() function

The function translate-space() removes all leading and trailing whitespace characters (spaces, new lines, tabs) and replaces neighboring whitespace characters inside a string with a single space.

Output of this shirts is formatted to HTML and browsers automatically coalesce neighboring whitespace characters. The visual appearance of the source code therefore does not correspond to actual source. The function translate() was used in this example to visualize changes. Spaces are replaced with "X", new lines with "Y" (entity 
).

XPAth 2.0 introduces function normalize-unicode() to normalize Unicode values. This function is useful for signs used in some languages but it is not useful for Czech characters.
