ParseError：嵌套形式

Question

Python的机械化给出嵌套形式的错误此代码：

url = 'http://bis.zju.edu.cn/psi/' 
browse = mechanize.Browser() 
browse.set_handle_robots(False) 
browse.open(url) 

# print [n for n in browse.forms()] 
# ParseError: nested FORMs 

browse.select_form(name="form1") # or (nr=0) 
# ParseError: nested FORMs 

seq = '>seq1' + '\n' + 'MNANSSAKLGDSA' 
browse['sequence'] = seq 
response = browse.submit() 

---

无论这解决了：

browse = mechanize.Browser(factory=mechanize.RobustFactory()) 
browse.set_handle_robots(False) 
browse.open(url) 

print [n for n in browse.forms()] 
# [] # empty list 

browse.select_form(name="form1") # or (nr=0) 
# FormNotFoundError: no form matching name 'form1' 

---

这也不：

browse = mechanize.Browser() 
browse.set_handle_robots(False) 
response = browse.open(url) 
# 'modify response' (anyway? to remove erroneous html?) 
browse.set_response(response) 

print [n for n in browse.forms()] 
# [] # empty list 

browse.select_form(name="form1") # or (nr=0) 
# FormNotFoundError: no form matching name 'form1'

我已经在python/mechanize在stackoverflow /其他论坛上搜索net的Q/A嵌套窗体错误。无解决方案。

任何（快速）帮助表示赞赏。谢谢。

看看this question，可能试着使用BeautifulSoup来解析网站，而不是自行机械化，BS更强大一点。
