    比如html页面有多个div 里面有不同的标签容器

    伪代码如下

    while True:
    re.search("<div",html);

    ....
    re.match("aa")
    or re.match("bb")
    ..

    没有do whilte ,只能用white True了 

    while True:
    m=p.search(text,index)
    if m==None:
    break
    print "\n matched"
    match= m.group()
    ....

    index= m.end()
