今天用到python解析xml文档，再改变数据之后，再保存会文件。
记录下代码：
import os,sys
from xml.dom.minidom import parse,Text
class DIYDom():
def __init__(self,path):
self.path = path
self.dom = self.toDOM(path)
def toDOM(self,path):
if os.path.isfile(path):
return parse(path)
return False
def getNode(self,uri,createFlag = False):
if uri[0] == "/":
uri = uri[1:]
if uri[-1] == "/":
uri = uri[:-1]
path = uri.split("/")
node = self.dom
existFlag = False
for p in path:
for n in node.childNodes:
if n.nodeName == p:
node = n
existFlag = True
break
if existFlag == False and createFlag == True:
node = self.createNode(node,p)
if existFlag == False and createFlag == False:
return False
existFlag = False
return node
def createNode(self,parentNode,nodeName):
return parentNode.appendChild(self.dom.createElement(nodeName))
def setText(self,uri,text,createFlag = False):
node = self.getNode(uri,createFlag)
if node == False:
return False
t = Text()
t.data = text
if node.firstChild == None:
node.appendChild(t)
else:
node.replaceChild(t,node.firstChild)
return True
def toXML(self):
domString = self.dom.toxml()
return domString
def saveXML(self):
xmlString = self.toXML()
xmlFile = open(self.path,"w")
try:
xmlFile.write(xmlString)
return True
finally:
xmlFile.close()
D = DIYDom("XML_NAME.zone.xml")
##node = D.getNode("/zone/extension/file")
D.setText("/zone/extension/files","testFile",True)
D.setText("/zone/extension/file","testFile",True)
D.setText("/zone/extension/propertiesFile","testFile",True)
print D.toXML()
XML_NAME.zone.xml的内容为：
<name>name</name>
<extension>
<name>testName</name>
<file>testFile</file>
<propertiesFile>testProperties</propertiesFile>
</extension>
