XML的例子

import xml.etree.ElementTree as ET

tree = ET.parse("test.xml")

root = tree.getroot()

print(root.tag)

# 遍历xml文档

for child in root:

    print(child.tag, child.attrib)

    for i in child:

        print(i.tag, i.text)

# 只遍历year 节点

for node in root.iter('year'):

    print(node.tag, node.text)

# ---------------------------------------

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)

    node.set("updated", "yes")

tree.write("test.xml")

# 删除node

for country in root.findall('country'):

    rank = int(country.find('rank').text)

    if rank > 50:

        root.remove(country)

tree.write('output.xml')

创建XML文件

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("test.xml", encoding="utf-8",xml_declaration=True)

ET.dump(new_xml) #打印生成的格式
