QT xml转ini的实现（从C#转到QT）

c# QT xml操作差异

why：接到需求把设备端的xml参数，转换为ini，做一个中间的数据结构，中转后，格式化保存为ini格式。c#写好了，但另外一个程序是qt写的

一 c#和QT在xml操作的差异差异

二实例解析的xml

三c#递归转换XML配置参数代码

四 QT递归转换XML配置参数代码

五 QT下xml转ini的代码

一 c#和QT在xml操作的差异差异 1 接口名变更，函数的首字母大小写 C#是( CreateElement) vs QT (createElement) 2 成员自动引用和QT的指针传递xml成员节点 3 属性的获取方式差异 C# 映射表获取（keyChild.Attributes["type"].Value） vs QT 接口获取（ keyChild.attribute("type").trimmed();） //属性值的获取<VALUE type="ENUM">1</VALUE>，如其中的type属性 c# keyChild.InnerText vs QT keyChild.text().trimmed(); //节点文本的获取<VALUE type="ENUM">1</VALUE>，如其中的“1” c# child.Name vs QT child.tagName() //标志的获取<VALUE type="ENUM">1</VALUE>，如其中的VALUE 4 对象名比较 XmlDocument vs QDomDocument XmlNode vs QDomNode XmlElement vs QDomElement 5 编码转换是公有的问题。是gbk 还是 utf-8 二实例解析的xml
