public intdoEndTag()
Gets the value, specified by the value attribute, the stringValue attribute, the param attribute, or the name and property attributes, and adds it to the parent's value list. If the value is a String and a pattern attribute is specified, the String is converted into the appropriate type before being added to the parent's value list.
