normalizeSpaces
Method that will check character array passed, and remove all "extra" spaces (leading and trailing space), and normalize other white space (more than one consequtive space character replaced with a single space).NOTE: we only remove explicit space characters (char code 0x0020); the reason being that other white space must have come from non-normalizable sources, ie. via entity expansion, and is thus not to be normalized
- Parameters:
buf
- Buffer that contains the String to checkorigStart
- Offset of the first character of the text to check in the bufferorigEnd
- Offset of the character following the last character of the text (as per usual Java API convention)- Returns:
- Normalized String, if any white space was removed or normalized; null if no changes were necessary.

isAllWhitespace
public static boolean isAllWhitespace(char[] ch, int start, int len) -
equalEncodings
Method that implements a loose String compairon for encoding Strings. It will work likeString.equalsIgnoreCase(java.lang.String)
, except that it will also ignore all hyphen, underscore and space characters. -
encodingStartsWith

isSpace
