                    }
                },
                parseUBB: function(node, sonString, setting) {
                    // parser will find a matched tag for you
                    // return UBB string include sonString
                    return '<div class="gui-ubb-ref">' + sonString + '</div>';

                // '' or undefined indicate it can't contian any tag.
                // '*' indicate it can contian any tag.
                canContains: 'bold,italic,color,url,image',
                // bool.
                // If true, then this tag can contains '\n'.
                canWrap: 0,
                // bool.
                // If true, then the '\n' right after this tag should be ignore.
                isBlock: 0,
                noAttr: 1
            }
        }
    });
// convert HTML element to UBB string
parser.HTMLtoUBB($('#container'));
// convert UBB string to HTML string
parser.UBBtoHTML('[bold]aaa[/bold]');
// auto correct UBB string
parser.fixUBB('[bold]aaa');   // ==> echo [bold]aaa[/bold]

Please check index.html for detail.

#NOTE: When converting HTML elements to UBB string, UBBParser can deal with whitespace and newline in pre style. But in case of IE 6/7/8's bug, it's not work very well in this situation.
