当美丽的汤4看起来不适合解析时该怎么办？它无法找到输入

时间：2016-10-21 20:11:10

标签： python html beautifulsoup

我目前正在使用Beautiful Soup 4在Python 2.7.x上尝试通过按名称查找输入来解析旧的html页面，但Beautiful Soup不会返回我正在寻找的输入。它返回一堆其他代码，而不仅仅是＆＃34; a_dev＆＃34;隐藏的输入。我被引导相信它，因为html没有按照Beautiful Soup寻找的方式进行格式化;但是，html是有效的。我在这里错过了什么吗？

我试图获取名为＆＃34; a_dev＆＃34;的隐藏输入的值。

我的代码段在这里：

try:
    alarmPage = beautifulSoup(urllib2.urlopen(url, timeout=4).read(), 'html.parser')
    print '====== alarm page ======'
    print alarmPage
    print '====================='
    inputs = alarmPage.find_all("input", {"name":"a_dev"})
    print '====== alarms ======'
    print inputs
    print '====================='
    for i in inputs:
        print '========== i ==========='
        print i
        print '========== end i ========='

    return False, inputs
except urllib2.HTTPError as e:
    traceback.print_exc()
    return True, None
...

alarmPage =
