python – 为嵌套模式解析字符串

但是,请注意,XML元素名称不能以您的示例所具有的数字开头.

这是一个可以满足你需要的解析器,虽然你需要调整它以将重复的元素组合成一个dict键：

from xml.parsers.expat import ParserCreate

open_elements = {}
result_dict = {}

def start_element(name,attrs):
    open_elements[name] = True

def end_element(name):
    del open_elements[name]

def char_data(data):
    for element in open_elements:
        cur = result_dict.setdefault(element,'')
        result_dict[element] = cur + data

if __name__ == '__main__':
    p = ParserCreate()

    p.StartElementHandler = start_element
    p.EndElementHandler = end_element
    p.CharacterDataHandler = char_data

    p.Parse(u'<_133_3><_135_3><_116_2>The other system worked for about 1 month</_116_2> got some good images <_137_3>on it then it started doing the same thing as the first one</_137_3> so then I quit using either camera now they are just sitting and collecting dust.</_135_3></_133_3>',1)

    print result_dict
