Python解析XML字符串(将XML转换成为dict类型)

import xml.sax
import xml.sax.handler


class XMLHandler(xml.sax.handler.ContentHandler):
    def __init__(self):
        self.buffer = ""
        self.mapping = {}

    def startElement(self, name, attributes):
        self.buffer = ""

    def characters(self, data):
        self.buffer += data

    def endElement(self, name):
        self.mapping[name] = self.buffer

    def getDict(self):
        return self.mapping


data = '<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>'

xh = XMLHandler()
xml.sax.parseString(data, xh)
ret = xh.getDict()
print(type(ret))
print(ret)
print(ret['return_code'])

从django请求中获取到xml数据,解析成为dict数据

class test_xml(View):
    def get(self, request):
        result = request.body.decode()
        print(result)
        xh = XMLHandler()
        xml.sax.parseString(result, xh)
        ret = xh.getDict()
        print(ret['return_code'])
        # 接收xml数据
        return HttpResponse('ok')

django 类视图返回xml数据

class transition(View):
    def get(self, request):
        xml_data = """<xml>
            <return_code>{return_code}</return_code>
            <result_code>{result_code}</result_code>
            </xml>
        """
        return HttpResponse(xml_data,content_type='text/xml')
