Following is the description of filter available * 1) email : validate the confirmance of the value against an email format * 2) userid : validate the confirmance of the value against the format of user id. (combination of number[0-9],alphabet(lower case) and '_', underscore starting with an alphatic character) * 3) alpha : check if the value is consists of alphabatic characters. * 4) number : check if the value is consists of numerical digits * 5) equalto = target : indicate that values in the form should be equal to those in target * * - parameter - param * name = key : indicate that a new array, 'key' will be created and a value will be assigned to it * target = target_name : target form element의 값을 가져옴 * * - response * tag = key : name of variable that will contain the result of the execution * } **/ class XmlJsFilter extends XmlParser { var $version = '0.2.4';
