ParseError:嵌套的窗体 [英] ParseError: nested FORMs

问题描述

Python机械化为此代码提供嵌套的FORMs错误:

Python mechanize gives nested FORMs error for this code:

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()

---

这都不能解决:

---

Neither this solves:

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'

---

也不是:

---

Nor this:

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/其他论坛中搜索了嵌套形式错误的Q/A.没有解决办法.

I have searched net for Q/A on nested forms error in python/mechanize in stackoverflow/ other forums. No solutions.

感谢任何(快速)帮助.谢谢.

Any (quick) help is appreciated. Thanks.

推荐答案

看看这个问题，并可能尝试使用 BeautifulSoup 来解析网站，而不是机械化本身，BS会更健壮.

Take a look at this question, and possibly try using BeautifulSoup to parse the website instead of mechanize itself, BS is a little bit more robust.
