因为要处理的格式为一个标准的html table，用正则处理起来既麻烦又效率不高，可以尝试用其他方法游册，比如像这样，把得到的结果放到一个隐藏的div中，转换为html数据，在通过html的相关方法来处理数据，较为方便和清晰
Javascript正则表达式:<tr><tds+class=name>(.*?)</td><tds+class=xingbie>(.*?)</td>(<tds+class=dengji>(.*?)</td>)?(<tds+class=zhiye>(.*?)</td>)?</tr>
完整的Javascript程序如下:
<script type="text/javascript">
纯正 var str="<table><tr><td class=name>李四</td><td class=xingbie>男</td><td class=dengji>VIP</td><td class=zhiye>教师</td></tr><tr><td class=name>张三<穗裤激/td><td class=xingbie>男</td><td class=dengji>VIP</td></tr><tr><td class=name>王二</td><td class=xingbie>女</td></tr></table>";

var s = "你的字符串";
var reg1 = /<tr>(?:(?!</tr>).)*</tr>/gi;

var result = [];
while(a1 = reg1.exec(s)){
手戚 var obj = 悉斗{};
while(a2 = reg2.exec(a1[0])){
obj[a2[1]] = 毕陆陵a2[2];
}
result.push(obj);
}
//运行结果是 result 集合，单个元素是 {dengji : "", name : "", xingbie: "", zhiye: ""}
