1.XML基本概念 XML指可扩展语言(eXtensible Markup Language),用来传输和存储数据,一个XML文件分为如下几部分内容: 1)文档声明 2)元素 3)属性 4)注释 5)CDATA区 6)实体 1.1 文档声明 在编写XML文档时,需要先使用文档声明,声明XML文档的类型。最简单的声明语法:<?xml version="1.0" encoding="UTF-8"?>,...

xml.etree.ElementTree.dump(elem) Writes an element tree or element structure to sys.stdout. This function should be used for debugging only. The exact output format is implementation dependent. In this version, it’s written as an ordinary XML file. ...

Python has an in-built function called open() to open a file. It takes a minimum of one argument as mentioned in the below syntax. The open method returns a file object which is used to access the write, read and other in-built methods. ...
