python lxml.etree._Element 到 JSON 或 dict

Question

From one method of library I get lxml.etree._Element , is there any library or function to convert an lxml.etree._Element to JSON or a dictionary?

For example:

<detail>
    <ouaf:Fault xmlns:ouaf="urn:oracle:ouaf">
        <ResponseStatus>F</ResponseStatus>
        <ResponseCode>2013</ResponseCode>
        <ResponseData numParm="1"  text="The personal account was not found: 9134211141"  category="90006"  number="32200"  parm1="9134211141"  />
    </ouaf:Fault>
</detail>

Should be something like this:

{
    'detail': {
        'Fault': {
            'ResponseStatus': 'F'
            'ResponseCode': '2013'
            'ResponseData': {
                'numParm': '1'
                'text': 'The personal account was not found: 9134211141'
                'category': '90006'
                'number': '32200'
                'parm1': '9134211141'
            }           
        }
    }
}

Update 1:

When I trying use this function

def conver_element(self, element):
        foo = self.recursive_dict(element)
        return foo

def recursive_dict(self, element):
    return element.tag, \
           dict(map(self.recursive_dict, element)) or element.text

And I get foo:

<class 'tuple'>: ('detail', {'ResponseCode': '2013', 'ResponseStatus': 'F', 'ResponseData': None})

The recursive_dict method in the linked documentation doesn't include XML attribute in the result. Assuming, for XML element that has attribute and doesn't have content (self-closing tag) you want to get the attributes as the dictionary value, the following modified version of recursive_dict will do :

def recursive_dict(element):
    if element.text == None and len(element.attrib):
        return element.tag, element.attrib
    return element.tag, \
            dict(map(recursive_dict, element)) or element.text
