利用python 创建XML文件

#coding=utf-8
from xml.etree import ElementTree

import pdb

def printNodeInfo(node):

    #node.tag 标签名称
    #node.text 文本属性
    print 'node.tag: %s' %node.tag

    #node.attrib 属性字典
    for key in node.attrib:
        print '%s %s' %(key,node.attrib[key])
    return None

def main():

    pdb.set_trace()
    try:
        #ElementTree.parse(source,parser=None)
        #将xml文件加载并返回ElementTree 对象
        #parser 是一个可选的参数，如果为空则使用标准的XMLParser
        #step 1: 获取 ElementTree 对象
        xmlDoc = ElementTree.parse('D:servermapApp.xml')
        #step 2: 获取 根节点
        root = xmlDoc.getroot()
        #root.getchildren() 获取节点 返回的是列表
        gateServerNodeList = root.getchildren()

        # 下面是在每个gateServer 节点下 增加一个子节点
        for node in gateServerNodeList:
            # ElementTree.SubElement(parentNode,tagName)
            #给parentNode 增加一个子节点
            #和parentNode.append(Element) 效果一致
            newNode = ElementTree.SubElement(node,'ActiveType')
            # 设置属性 
            newNode.attrib['id'] = '9'
            newNode.attrib['level'] = '38'
            newNode.attrib['begin'] = '201401010000'
            newNode.attrib['end'] = '201401010000'
            #中文 需要 特殊译码
            newNode.attrib['tip'] = '测试'.decode('utf-8')
            #节点尾部的符号
            newNode.tail = '
'
            #node.append(newNode)

        # 写入文件 调用 之前的ElementTree 对象的
        #write(fileName,encoding = None,xml_Decleare = None,default_namespace = None,method = None)
        # 其中xml_Decleare 如果为 True 则 在 文档的最上方会写入
        #<?xml version="1.0" encoding="utf-8"?>
        xmlDoc.write('D:test.xml','utf-8',True)
    except Exception as e:
        print e
        
    return None

if __name__ == '__main__':
    main()

from xml.etree import ElementTree as ET

tree = ET.parse('first.xml')

root = tree.getroot()
# print(root.tag)
# print(root.attrib)
# print(root.text)
# 创建节点，element类型
son = root.makeelement('tt',{'vv':'KK'})
s = son.makeelement('tt',{'kk':'132443'})
# son = ET.Element('tt',{'vv':'KK'})
# s = ET.Element('tt',{'kk':'132443'})
son.append(s)
root.append(son)
tree.write('out.xml')

 简单创建xml

from xml.etree import ElementTree as ET

root = ET.Element('root',{'age':'18'})

son=ET.SubElement(root,'root',{'age':'18'})
ET.SubElement(son,'haha',{'bb':'fhfhf'})

tree = ET.ElementTree(root)
tree.write('aha.xml')

结果

<root age="18">
    <root age="18">
        <haha bb="fhfhf" />
    </root>
</root>
