The passed string gets normalized along the rules for the given locale as they are set in the file "./normalization.xml". If such rules are specified, the following order is obeyed:

1. if the attribute "case" is set with "toLower" or "toUpper", the letters are switched to lower case or to upper case respectively.
2. all rules given in the "Rule" elements are performed.
3. if the attribute "removeDoubles" is set and not empty, all multi occurences of the letters given in this attribute are reduced to a single occurence.

Parameters:

source - the String to normalize

locale - the locale language defining the rules to choose, e.g. "de"

Returns:

the normalized String

Throws:

IOException

SAXException

XMLParsingException
