我有以下格式的html文件。我想用python解析它。但是，我对使用 xml 模块一无所知。非常欢迎您的建议。

注意：再次对不起我的无知。问题不具​​体。但是，由于我对这样的解析脚本感到沮丧，我确实想得到一个由答案人（谢谢大家）描述的具体答案作为起点。希望你能理解。

我建议你看看 Python 库BeautifulSoup。它可以帮助您导航和搜索 HTML 数据。

我这样做是为了锻炼。如果这仍然有用，它应该让你走上正确的轨道。

data = []
soup = BeautifulSoup(html)
divs = soup.findAll('div')
for div in divs:
    div_string = str(div)
    div_string = div_string.replace('<br />', '')
    div_list = div_string.split('\n')
    div_list = div_list[1:-1]
    record = []
    for item in div_list:
        record.append( tuple(item.split(':', 1)) )
    data.append(record)

for record in data:
    for field in record:
        print field
    print '--------------'

使用您的样本数据，您将获得此输出。进一步处理应该很容易按摩到您想要的任何结构中。
