利用python 创建XML文件

 1 #coding=utf-8
 2 from xml.etree import ElementTree
 3 
 4 import pdb
 5 
 6 def printNodeInfo(node):
 7 
 8     #node.tag 标签名称
 9     #node.text 文本属性
10     print 'node.tag: %s' %node.tag
11 
12     #node.attrib 属性字典
13     for key in node.attrib:
14         print '%s %s' %(key,node.attrib[key])
15     return None
16 
17 def main():
18 
19     pdb.set_trace()
20     try:
21         #ElementTree.parse(source,parser=None)
22         #将xml文件加载并返回ElementTree 对象
23         #parser 是一个可选的参数，如果为空则使用标准的XMLParser
24         #step 1: 获取 ElementTree 对象
25         xmlDoc = ElementTree.parse('D:servermapApp.xml')
26         #step 2: 获取 根节点
27         root = xmlDoc.getroot()
28         #root.getchildren() 获取节点 返回的是列表
29         gateServerNodeList = root.getchildren()
30 
31         # 下面是在每个gateServer 节点下 增加一个子节点
32         for node in gateServerNodeList:
33             # ElementTree.SubElement(parentNode,tagName)
34             #给parentNode 增加一个子节点
35             #和parentNode.append(Element) 效果一致
36             newNode = ElementTree.SubElement(node,'ActiveType')
37             # 设置属性 
38             newNode.attrib['id'] = '9'
39             newNode.attrib['level'] = '38'
40             newNode.attrib['begin'] = '201401010000'
41             newNode.attrib['end'] = '201401010000'
42             #中文 需要 特殊译码
43             newNode.attrib['tip'] = '测试'.decode('utf-8')
44             #节点尾部的符号
45             newNode.tail = '
'
46             #node.append(newNode)
47 
48         # 写入文件 调用 之前的ElementTree 对象的
49         #write(fileName,encoding = None,xml_Decleare = None,default_namespace = None,method = None)
50         # 其中xml_Decleare 如果为 True 则 在 文档的最上方会写入
51         #<?xml version="1.0" encoding="utf-8"?>
52         xmlDoc.write('D:test.xml','utf-8',True)
53     except Exception as e:
54         print e
55         
56     return None
57 
58 if __name__ == '__main__':
59     main()

 1 from xml.etree import ElementTree as ET
 2 
 3 tree = ET.parse('first.xml')
 4 
 5 root = tree.getroot()
 6 # print(root.tag)
 7 # print(root.attrib)
 8 # print(root.text)
 9 # 创建节点，element类型
10 son = root.makeelement('tt',{'vv':'KK'})
11 s = son.makeelement('tt',{'kk':'132443'})
12 # son = ET.Element('tt',{'vv':'KK'})
13 # s = ET.Element('tt',{'kk':'132443'})
14 son.append(s)
15 root.append(son)
16 tree.write('out.xml')

简单创建xml

1 from xml.etree import ElementTree as ET
2 
3 root = ET.Element('root',{'age':'18'})
4 
5 son=ET.SubElement(root,'root',{'age':'18'})
6 ET.SubElement(son,'haha',{'bb':'fhfhf'})
7 
8 tree = ET.ElementTree(root)
9 tree.write('aha.xml')

结果

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