C++ 增删改查xml

之前需要下载别人开发好的资源：TinyXML download | SourceForge.net

 

然后在你的工程中引入以下6个文件，并且在使用的时候包含两个头文件：

 

 

 

下面就是在按钮响应函数中运用了。

创建xml

void BuilderXml()
{
    TiXmlDocument xmlDocument;

    xmlDocument.LinkEndChild(new TiXmlDeclaration("1.0", "UTF-8", ""));

    TiXmlElement *XmlRoot = new TiXmlElement("root");
    xmlDocument.LinkEndChild(XmlRoot);


    TiXmlElement *XmlChild1 = new TiXmlElement("name");
    XmlRoot->LinkEndChild(XmlChild1);
    XmlChild1->SetAttribute("id", "0001");
    XmlChild1->LinkEndChild(new TiXmlText("value 1"));


    TiXmlElement *XmlChild2 = new TiXmlElement("name");
    XmlRoot->LinkEndChild(XmlChild2);


    TiXmlElement *XmlChild2_01 = new TiXmlElement("name2");
    XmlChild2->LinkEndChild(XmlChild2_01);
    XmlChild2_01->LinkEndChild(new TiXmlText("value 2_01"));

    TiXmlElement *XmlChild2_02 = new TiXmlElement("name2");
    XmlChild2->LinkEndChild(XmlChild2_02);
    XmlChild2_02->LinkEndChild(new TiXmlText("value 2_02"));

    xmlDocument.SaveFile("new.xml");

}

删除xml

void DelXml()
{
    TiXmlDocument xmlDocument;


    if(!xmlDocument.LoadFile("D:/MFC/XmlParseAndPrint/XmlParseAndPrint/new.xml"))
    {
        return;
    }

    TiXmlElement *XmlRoot = xmlDocument.RootElement();

    TiXmlElement *element = XmlRoot->FirstChildElement("name");

    element->RemoveAttribute("id");
    XmlRoot->RemoveChild(element);

    xmlDocument.SaveFile("new.xml");
}

修改xml

void ModifyXml()
{
    TiXmlDocument xmlDocument;

    if(!xmlDocument.LoadFile("D:/MFC/XmlParseAndPrint/XmlParseAndPrint/new.xml"))
    {
        return;
    }

    TiXmlElement *XmlRoot = xmlDocument.RootElement();

    TiXmlElement *element = XmlRoot->FirstChildElement("name");

    element->SetValue("modify");

    element->SetAttribute("id", "modify id");

    xmlDocument.SaveFile("new.xml");
}

显示xml

void DisplayXml(const char *dbname)
{
    TiXmlDocument xmlDocument;

    if(!xmlDocument.LoadFile("D:/MFC/XmlParseAndPrint/XmlParseAndPrint/new.xml"))
    {
        return;
    }

    TiXmlElement *XmlRoot = xmlDocument.RootElement();


    for(TiXmlElement *element = XmlRoot->FirstChildElement(dbname); element != NULL; element = element->NextSiblingElement())
    {


        //const char* arr = element->Attribute("name");
        const char* node1Name = element->GetText();

        for(TiXmlElement *elementChild = element->FirstChildElement(); elementChild != NULL; elementChild = elementChild->NextSiblingElement())
        {
            //const char* name = elementChild->Attribute("name2");
            const char* node2Name = elementChild->GetText();
        
            int  k = 0;

        }

        int j = 0;
    }
}

最后在需要的地方添加函数使用就好了，实际根据需求再修改xml代码
