python 修改xml节点值

from xml.etree import ElementTree filePath = 'd:\\aaa.xml' xmldoc = ElementTree.parse(filePath) node = xmldoc.find('./string') node.text = "win 7" 其实说实话,楼上的回答已经很清楚了. 不管什么编程语言,要想学好,基础一定要扎实.

类似于:#!/usr/bin/evn python #coding:utf-8 try: import xml.etree.cElementTree as ET except ImportError: import xml.etree.ElementTree as ET import sys try: tree = ET.parse("country.xml") #打开xml文档 #root = ET.fromstring(count...

使用python自带的ElementTree模块,给你个例子你就知道了 xml文档 0 E:/Python Python 代码,修改id节的内容 from xml.etree import ElementTree xml_file='config.xml' xml=ElementTree.ElementTree(file=xml_file).getroot() xml.find('id').t...

其实python有解析xml的模块 只是你这个xml文件太简单,字符串处理就够了 还是一样,按行搜索,加个flag,读到b并且attr=2是flag=1 如果flag=1且本行是就替换数值,flag=0 等循环完了,写入新文件就行

fpr=open("text.txt") data=fpr.read() n=0 for i in range(len(data)): if data[i]=='/' and data[i+1]=='>': n+=1 newdata=data[0:i]+str(n)+'>a'+str(n)+'fora' k=i break for i in range(k+1,len(data)): if data[i]=='/' and data[i+1]=='>...

这里的4是作为maxid的子字节点存在的,所以你需要再遍历一层 dom = xml.dom.minidom.parse('c:/12345.xml')root = dom.documentElementfor rt in root.childNodes: if rt.nodeName == 'maxid': for node in rt.childNodes: print node.nodeValue...

XML code E:/Python from xml.etree import ElementTreexml_file='config.xml'xml=ElementTree.ElementTree(file=xml_file).getroot()xml.find('id').text=1xml.write("output.xml")

#!/usr/bin/evn python #coding:utf-8 try: import xml.etree.cElementTree as ET except ImportError: import xml.etree.ElementTree as ET import sys try: tree = ET.parse("test.xml") #打开xml文档 root = tree.getroot() #获得root节点 ex...

假如我们有个xml文档如下:example.xml Matlab 2008-09-10 23:16:48 1,2,3;4,5,6;7,8,9 首先,要解析xml文档,需要导入一个模块 >>> from xml.dom.minidom import parse (1)然后载入一个xml文档 >>> xmldoc = parse("J:/homeword/example.xml"...
