        使用flex自身的RegExpValidator控件进行正则表达式校验十分方便，但是需要注意以下几点：
        1.必须用{''}将正则表达式括起来。
        2.所有的转义符号\都必须写成\\。
        3.大括号{}必须加转义符号。
        例：
        <mx:RegExpValidator id="regExpV" source="{str}" property="text"
        flags="g" expression="{'^[1-9](\\d*\\.\\d\{1,2\}|\\d*)$'}" noMatchError="版本形式不合法"/>
