Question

我正在尝试构建一个实用程序函数来向浏览器输出漂亮的汤代码我有以下代码：

def bs4_to_browser(data):

    from selenium import webdriver
    driver = webdriver.Firefox(path="F:\FirefoxPortable\Firefox.exe")
    driver.get("about:blank")
    # data = '<h1>test</h1>'  # supposed to come from BeautifulSoup -- this works when uncommented

    driver.execute_script('document.body.innerHTML = "{html}";'.format(html=data))
    return

>>> listing
<div class="listingHeader">
....
>>> type(listing)
<class 'bs4.element.Tag'>
>>> a = unicode(listing)
>>> type(a)
<type 'unicode'>

现在如果我跑：

>>> bs4_to_browser(a)
Traceback (most recent call last):

    raise exception_class(message, screen, stacktrace)
WebDriverException: Message: u'missing ; before statement' ; Stacktrace: 
    at handleEvaluateEvent (about:blank:68:11)

我该如何解决这个问题？

关于评论：

1）WebDriverException：消息：u'syntax error'; Stacktrace：由linechange生成。

2）

>>> a = unicode(listing)
>>> a = a.replace('\n', '')
>>> bs4_to_browser(a)

3）我正在使用FF 31.1 ESR portable和selenium 2.42.1

我还注意到，如果在运行bs4_to_browser之前浏览器没有完全关闭，你会得到：“WebDriverException：消息：'浏览器似乎已经退出，然后才能连接。输出为：'”

WebDriverException：消息：u'missing;在声明之前';
