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:\server\map\App.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'] = ''
             newNode.attrib['level'] = ''
             newNode.attrib['begin'] = ''
             newNode.attrib['end'] = ''
             #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 = '\n'
             #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':''})
 # 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':''})

 son=ET.SubElement(root,'root',{'age':''})
 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>
