characters method on the passed ContentHandler for the
string-value. | | public boolean | endsWith(String suffix)

case using the rules of the default locale, which is returned
by Locale.getDefault.
If no character in this string has a different uppercase version,
based on calling the toUpperCase method defined by
Character, then the original string is returned.
Otherwise, this method creates a new String object
representing a character sequence identical in length to the
character sequence represented by this String object and
with every character equal to the result of applying the method
Character.toUpperCase to the corresponding character of
this String object. | | public XMLString | trim()
Removes white space from both ends of this string.
If this String object represents an empty character
sequence, or the first and last characters of character sequence
represented by this String object both have codes
greater than '\u0020' (the space character), then a
reference to this String object is returned.
Otherwise, if there is no character with a code greater than
'\u0020' in the string, then a new
String object representing an empty string is created
and returned.
Otherwise, let k be the index of the first character in the
string whose code is greater than '\u0020', and let
m be the index of the last character in the string whose code
is greater than '\u0020'. |

All strings of white space are
replaced by a single space character (#x20), except spaces after punctuation which
receive double spaces if doublePunctuationSpaces is true.

results, the formatter should probably do it's own white space handling
based on the semantics of the formatting object.

the string itself. |
| toUpperCase | | public XMLString toUpperCase()(Code) | | Converts all of the characters in this String to upper
case using the rules of the default locale, which is returned
by Locale.getDefault.
If no character in this string has a different uppercase version,
based on calling the toUpperCase method defined by
Character, then the original string is returned.
Otherwise, this method creates a new String object
representing a character sequence identical in length to the
character sequence represented by this String object and
with every character equal to the result of applying the method
Character.toUpperCase to the corresponding character of
this String object.
Examples:
"Fahrvergnügen".toUpperCase() returns "FAHRVERGNÜGEN"

| trim | | public XMLString trim()(Code) | | Removes white space from both ends of this string.
If this String object represents an empty character
sequence, or the first and last characters of character sequence
represented by this String object both have codes
greater than '\u0020' (the space character), then a
reference to this String object is returned.
Otherwise, if there is no character with a code greater than
'\u0020' in the string, then a new
String object representing an empty string is created
and returned.
Otherwise, let k be the index of the first character in the
string whose code is greater than '\u0020', and let
m be the index of the last character in the string whose code
is greater than '\u0020'. A new String
object is created, representing the substring of this string that
begins with the character at index k and ends with the
character at index m-that is, the result of
this.substring(k, m+1).
This method may be used to trim
Character.isSpace(char) whitespace from the beginning and end
of a string; in fact, it trims all ASCII control characters as well.
