Python mechanize 忽略 HTML 中的表单输入

Question

得到我的小 Mechanize 代码:

br.open('http://tumblr.com/customize'); 
print br.response().read()
print br.form['edit_tumblelog[cname]'] # there definitely is edit_tumblelog
                                       # and br.form['edit_tumblelog[enable_cname]'] works fine

输出:

...
<br/>
                                    <input type="text" class="text_field" style="width:275px; min-width:0px;
                                    margin:6px 0px; border:solid 1px #d2d2d2;
                                    "
                                    name="cname" id="cname"
                                    onchange="form_changed = true;"
                                     value="blog.yay.com"    
                                    />
...
Traceback (most recent call last):
  File "/tmp/temp_textmate.W6p5gh", line 51, in <module>
    print br.form['edit_tumblelog[cname]']
  File "/Library/Python/2.6/site-packages/ClientForm-0.2.10-py2.6.egg/ClientForm.py", line 2891, in __getitem__

我做错了什么？

Answer 1

发现问题。这是 Mechanize HTML 解析器中的一个错误，它在 <br/> 出现后以某种方式忽略了下一个标签。注意 <br />工作正常。我的解决方案是手动替换那些:

response = br.response()
response.set_data(response.get_data().replace("<br/>", "<br />")) #Python mechanize is broken, fixing it.
br.set_response(response)

显然更好的解决方案是 re.sub() /> 之前没有空格的所有标签.
