fn:normalize-space(string)
fn:normalize-space()
Removes leading and trailing spaces from the specified string, and replaces all
internal sequences of white space with one and returns the result. If there is
no string argument it does the same on the current node
Example: normalize-space(' The XML ')
Result: 'The XML'
