python解析xml簡單示例
更新時間：2019年06月21日 09:31:31 作者：輕舞肥羊
這篇文章主要介紹了python解析xml,結合簡單實例形式分析了Python針對城市信息xml文件的讀取、解析相關操作技巧,需要的朋友可以參考下
本文實例講述了python解析xml的方法。分享給大家供大家參考，具體如下：
xml是除了json之外另外一個比較常用的用來做為數(shù)據(jù)交換的載體格式。對于一些比較固定的數(shù)據(jù)，直接保存在xml中，還可以免去去數(shù)據(jù)庫中查詢的麻煩。而且直接讀小文件，性能比查詢數(shù)據(jù)庫應該更好，下面一個例子，如何用python解析xml數(shù)據(jù)，xml數(shù)據(jù)是省份，城市 數(shù)據(jù)，內(nèi)容如下：

用python 代碼的解析方法如下：
import xml.dom.minidom
def get_citys():
city_xml = open(os.path.join(os.path.normpath(os.path.dirname(__file__)),'city.xml'))
doc = xml.dom.minidom.parse(city_xml)
citys = []
provinces = doc.getElementsByTagName('province')
for item in provinces:
entry = {'province':'','citys':[]}
province = item.getAttribute('name')
entry['province'] = province
for city in item.getElementsByTagName('city'):
city = city.getAttribute('name')
entry['citys'].append(city)
citys.append(entry)
return citys
這樣就可以解析出數(shù)據(jù)了，其他的類似。
