python中关于xmltodict的使用
Python中xmltodict使用
xml转换成OrderedDict
代码 :
import xmltodict
from pprint import pprint
xml = ('''
<mydocument has="an attribute">
<and>
<many>elements</many>
<many>more elements</many>
</and>
<plus a="complex" b="hello">
element as well
</plus>
</mydocument>
''')
pprint(xmltodict.parse(xml))
print(type(xmltodict.parse(xml)))
运行结果:
可以看到,代码将xml中所有的标签写到了一个OrderedDict中,并且可以运用字典的操作方法去任意取值
dict转换成xml
代码:
# 代码
dict1 = {'Request': {'Body': {'Name': '孙悟空',
'Province': '北京',
'SettlementFlag': '0001',
'Head': {'ID': '00000000',
'Code': '9999',
'No': '15533'}}}}
print(xmltodict.unparse(dict1))
运行结果:
xmltodict模块处理xml数据基本用法
xmltodict 是一个用来处理xml数据的很方便的模块。
包含两个常用方法parse和unparse
1. parse
xmltodict.parse()方法可以将xml数据转为python中的dict字典数据:
>>> import xmltodict
>>> xml_str = """
... <xml>
... <ToUserName><![CDATA[gh_866835093fea]]></ToUserName>
... <FromUserName><![CDATA[ogdotwSc_MmEEsjs9-ABZ1QL_4r4]]></FromUserName>
... <CreateTime>1478317060</CreateTime>
... <MsgType><![CDATA[text]]></MsgType>
... <Content><![CDATA[你好]]></Content>
... <MsgId>6349323426230210995</MsgId>
... </xml>
... """
>>>
>>> xml_dict = xmltodict.parse(xml_str)
>>> type(xml_dict)
<class 'collections.OrderedDict'> # 类字典型,可以按照字典方法操作
>>>
>>> xml_dict
OrderedDict([(u'xml', OrderedDict([(u'ToUserName', u'gh_866835093fea'), (u'FromUserName', u'ogdotwSc_MmEEsJs9-ABZ1QL_4r4'), (u'CreateTime', u'1478317060'), (u'MsgType', u'text'), (u'Content', u'\u4f60\u597d'), (u'MsgId', u'6349323426230210995')]))])
>>>
>>> xml_dict['xml']
OrderedDict([(u'ToUserName', u'gh_866835093fea'), (u'FromUserName', u'ogdotwSc_MmEEsJs9-ABZ1QL_4r4'), (u'CreateTime', u'1478317060'), (u'MsgType', u'text'), (u'Content', u'\u4f60\u597d'), (u'MsgId', u'6349323426230210995')])
>>>
>>> for key, val in xml_dict['xml'].items():
... print key, "=", val
...
ToUserName = gh_866835093fea
FromUserName = ogdotwSc_MmEEsJs9-ABZ1QL_4r4
CreateTime = 1478317060
MsgType = text
Content = 你好
MsgId = 6349323426230210995
>>>
2. unparse
xmltodict.unparse()方法可以将字典转换为xml字符串:
xml_dict = {
"xml": {
"ToUserName" : "gh_866835093fea",
"FromUserName" : "ogdotwSc_MmEEsJs9-ABZ1QL_4r4",
"CreateTime" : "1478317060",
"MsgType" : "text",
"Content" : u"你好",
"MsgId" : "6349323426230210995",
}
}
>>> xml_str = xmltodict.unparse(xml_dict)
>>> print xml_str
<?xml version="1.0" encoding="utf-8"?>
<xml><FromUserName>ogdotwSc_MmEEsJs9-ABZ1QL_4r4</FromUserName><MsgId>6349323426230210995</MsgId><ToUserName>gh_866835093fea</ToUserName><Content>你好</Content><MsgType>text</MsgType><CreateTime>1478317060</CreateTime></xml>
>>>
>>> xml_str = xmltodict.unparse(xml_dict, pretty=True) # pretty表示友好输出
>>> print xml_str
<?xml version="1.0" encoding="utf-8"?>
<xml>
<FromUserName>ogdotwSc_MmEEsJs9-ABZ1QL_4r4</FromUserName>
<MsgId>6349323426230210995</MsgId>
<ToUserName>gh_866835093fea</ToUserName>
<Content>你好</Content>
<MsgType>text</MsgType>
<CreateTime>1478317060</CreateTime>
</xml>
>>>
