Python 3 - HTML Parser - 从数据中制作字典

Question

如何从这些标签中获取数据字典：

<Currency_name>U.S. dollar</Currency_name>
<Observation_ISO4217>USD</Observation_ISO4217>
<Observation_date>2015-03-09</Observation_date>
<Observation_data>1.2598</Observation_data>
<Observation_data_reciprocal>0.7938</Observation_data_reciprocal>

例如我想要一个像{U.D. dollar: [USD, 2015-03-09, 1.2598,0.7938]} 这样的字典

我正在使用

def handle_starttag(self, tag, attrs):
    self.dic = {}
    if tag == 'currency_name':
        self.dic[currency_name] = handle_data()`

def handle_data: 
    return data

那么你可以使用XML PARSER这里一个例子

a='''<?xml version="1.0"?>
<data>
<country name="Liechtenstein">
    <rank>1</rank>
    <year>2008</year>
    <gdppc>141100</gdppc>
    <neighbor name="Austria" direction="E"/>
    <neighbor name="Switzerland" direction="W"/>
</country>
<country name="Singapore">
    <rank>4</rank>
    <year>2011</year>
    <gdppc>59900</gdppc>
    <neighbor name="Malaysia" direction="N"/>
</country>
<country name="Panama">
    <rank>68</rank>
    <year>2011</year>
    <gdppc>13600</gdppc>
    <neighbor name="Costa Rica" direction="W"/>
    <neighbor name="Colombia" direction="E"/>
</country>
</data>'''

 import xml.etree.ElementTree as ET
 root=ET.fromstring(a)
 #to parse from file use ET.parse('country_data.xml')

 b={}
 for child in root:
    b.update({child[0].text:[child[i].text for i in range(1,len(child)-2)]})
    b[child[0].text].extend(value for neighbor in child.iter('neighbor') for k,value in neighbor.items())

输出

b= {'4': ['2011', 'N', '马来西亚'], '68': ['2011', '13600', 'W', '哥斯达黎加', 'E', '哥伦比亚'], '1': ['2008', '141100', 'E', '奥地利', 'W', '瑞士']}
