[练习题]提取合法有效的身份证日期(练习题)

<h2>请将提取合法有效的身份证日期提取出来,请也许会说,身份证取日期公式一搜索,一大把,是的,确实是这样,但没有一个完整全面的公式,大家用起来不方便,大家练习一下,把附件中合法的身份证中的日期提取出来,错误的就显示错误.</h2>

做到"完整全面"估计相当难,只以18位身份证为例,常规的判断有:1,长度是否正确,2.日期是否是存在的日期. 要满足是合法的身份证号码,还要判断地址码(前六位数)是否按照按GB/T2260的规定执行.第二校验码是否正确. 这里转下身份证第18位校验码的规则:某男性公民身份号码本体码为34052419800101001，首先按照公式⑴计算： ∑(ai×Wi)(mod 11)……………………………………(1) 公式(1)中： i----表示号码字符从由至左包括校验码在内的位置序号； ai----表示第i位置上的号码字符值； Wi----示第i位置上的加权因子，其数值依据公式Wi=2（n-1）(mod 11)计算得出。 <table cellspacing="0" cellpadding="0" width="508" border="0" xstr="" style="WIDTH: 381pt;
