BeautifulSoup 获取 script 元素中的 javascript 代码

不能使用 ele.get_text()，需要使用 ele.contents。

    soup = None
    with open(filename, "rb") as f:
        content = f.read()
        soup = BeautifulSoup(content, "html.parser")
    if not soup:
        print("parse file failed: {}".format(filename), file=sys.stderr)
        return 0
    for s in soup.find_all("script"):
        for c in s.contents:
            print(c)
