这篇文章主要介绍了深入了解python之Xml操作,小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
读取xml内容：
-*- coding:utf-8 -*-
# Author: Evan Mi
import xml.etree.ElementTree as ET
tree = ET.parse('test.xml')
root = tree.getroot()
print(root.tag)
# 一个节点有tag、attrib、text三个值
# tag是标签的名字
# text是标签的内容
# attrib是标签属性的字典，通过字典的get('key')来获取对应的属性的值
# 直接for chile in parent 来遍历节点下的子节点
for child in root:
print(child.tag, child.attrib)
for elem in child:
print(elem.tag, elem.text, elem.attrib)
# 只遍历year节点
for node in root.iter('year'):
print(node.tag, node.text)生成xml内容：
# -*- coding:utf-8 -*-
# Author: Evan Mi
import xml.etree.ElementTree as ET
new_xml = ET.Element('namelist')
name = ET.SubElement(new_xml, 'name', attrib={'enrolled': 'yes'})
age = ET.SubElement(name, 'age', attrib={'checked': 'no'})
sex = ET.SubElement(name, 'sex')
sex.text = '33'
name2 = ET.SubElement(new_xml, 'name', attrib={'enrolled': 'no'})
age = ET.SubElement(name2, 'age')
age.text = '19'
et = ET.ElementTree(new_xml) # 生成文档对象
et.write('te.xml', encoding='utf-8', xml_declaration=True)
ET.dump(new_xml) # 打印生成的格式修改、删除xml内容：
# -*- coding:utf-8 -*-
# Author: Evan Mi
import xml.etree.ElementTree as ET
tree = ET.parse('test.xml')
root = tree.getroot()
# 修改
for node in root.iter('year'):
new_year = int(node.text) + 1
node.text = str(new_year) # 修改内容
node.set("updated", "yes") # 修改属性
tree.write('tt.xml')
# 删除
for country in root.findall('country'):
rank = int(country.find('rank').text)
if rank > 50:
root.remove(country)
tree.write('tt1.xml')相关推荐：
