讀取xml內容：

-*- coding:utf-8 -*- # Author: Evan Mi import xml.etree.ElementTree as ET tree = ET.parse('test.xml') root = tree.getroot() print(root.tag) # 一個節(jié)點有tag、attrib、text三個值 # tag是標簽的名字 # text是標簽的內容 # attrib是標簽屬性的字典，通過字典的get('key')來獲取對應的屬性的值# 直接for chile in parent 來遍歷節(jié)點下的子節(jié)點 for child in root:print(child.tag, child.attrib)for elem in child:print(elem.tag, elem.text, elem.attrib)# 只遍歷year節(jié)點 for node in root.iter('year'):print(node.tag, node.text)

生成xml內容：

# -*- coding:utf-8 -*- # Author: Evan Mi import xml.etree.ElementTree as ETnew_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) # 生成文檔對象 et.write('te.xml', encoding='utf-8', xml_declaration=True)ET.dump(new_xml) # 打印生成的格式

修改、刪除xml內容：

# -*- coding:utf-8 -*- # Author: Evan Mi import xml.etree.ElementTree as ETtree = ET.parse('test.xml') root = tree.getroot()# 修改 for node in root.iter('year'):new_year = int(node.text) + 1node.text = str(new_year) # 修改內容node.set("updated", "yes") # 修改屬性tree.write('tt.xml')# 刪除 for country in root.findall('country'):rank = int(country.find('rank').text)if rank > 50:root.remove(country) tree.write('tt1.xml')
