标题: Python网络编程基础笔记-minidom解析XML文件
1.python解析XML文件

"""
解析XML文件
1.Element XML树的节点
2.Text代表文本,包括Element的换行符
3.scanNode为一递归函数,如果当前的节点有子节点,进行递归调用
4.Node的类型
ELEMENT_NODE             = 1
ATTRIBUTE_NODE             = 2
TEXT_NODE                = 3
CDATA_SECTION_NODE       = 4
ENTITY_REFERENCE_NODE    = 5
ENTITY_NODE                = 6
PROCESSING_INSTRUCTION_NODE = 7
COMMENT_NODE             = 8
DOCUMENT_NODE             = 9
DOCUMENT_TYPE_NODE       = 10
DOCUMENT_FRAGMENT_NODE    = 11
NOTATION_NODE             = 12
"""
from xml.dom import minidom,Node
Node.TEXT_NODE
def scanNode(node,level = 0):
msg = node.__class__.__name__
if node.nodeType == Node.ELEMENT_NODE:
      msg += ",tag" + node.tagName
print " " * level * 4,msg
if node.hasChildNodes:
      for child in node.childNodes:
         scanNode(child,level + 1)
doc = minidom.parse("JCSample.xml")
scanNode(doc)
2.测试使用的XML
?xml version="1.0" encoding="UTF-8"?>
