使用tinyxml创建xml

Question

我有个问题。我需要创建以下xml：

<?xml version="1.0" encoding="utf-8"?>
<MyApp value="5" name="me">
</MyApp>

使用c ++代码，我执行了以下操作：

#include <iostream>
#include <string>
#include "tinyxml.h" 
void main(){
    TiXmlDocument doc;
    TiXmlDeclaration * decl = new TiXmlDeclaration( "1.0", "utf-8", "");
    doc.LinkEndChild( decl );

    TiXmlElement * root;
    root = new TiXmlElement( "MyApp" );  
    root->SetAttribute("value","5");
    root->SetAttribute("name","me");
    doc.LinkEndChild( root );  

    doc.SaveFile( "madeByHand.xml" );
    return 0;
}

我使用g ++ tinyxml.cpp tinyxmlerror.cpp和tinyxmlparser.cpp编译它。当我想查看我创建的XML时。我有一个错误：它说没有写清楚。我在哪里错？:)

万一有人需要这样的XML文件结构，以防万一：

<?xml version="1.0" ?>
<Hello>Opening a new salutation
   <Greeting value="5" name="me"></Greeting>
</Hello>

_

因此，这是此代码：

_

TiXmlDocument doc;
TiXmlDeclaration* decl = new TiXmlDeclaration( "1.0", "", "" );
doc.LinkEndChild( decl );

TiXmlElement* element = new TiXmlElement( "Hello" );
doc.LinkEndChild( element );

TiXmlText* text = new TiXmlText( "Opening a new salutation" );
element->LinkEndChild( text );

TiXmlElement* element2 = new TiXmlElement( "Greeting" );
element2->SetAttribute("value","5");
element2->SetAttribute("name","me");
element->LinkEndChild( element2 );

TiXmlText* text2 = new TiXmlText( "" );
element2->LinkEndChild( text2 );

doc.SaveFile( "madeByHand2.xml" );

_

还有一个选项，如何使用循环（for / while）添加一个以上的元素：

_

<?xml version="1.0" ?>
<Hello>Opening a new salutation
    <Greeting value="5" name="me"></Greeting>
    <Greeting value="5" name="me"></Greeting>
    <Greeting value="5" name="me"></Greeting>
</Hello>

_

这是此代码：

_

TiXmlDocument doc;
TiXmlDeclaration* decl = new TiXmlDeclaration( "1.0", "", "" );
doc.LinkEndChild( decl );

TiXmlElement* element = new TiXmlElement( "Hello" );
doc.LinkEndChild( element );

TiXmlText* text = new TiXmlText( "Opening a new salutation" );
element->LinkEndChild( text );


for(long i=0; i<3; i++)
{
TiXmlElement* element2 = new TiXmlElement( "Greeting" );
TiXmlText* text2 = new TiXmlText( "" );

element2->SetAttribute("value","5");
element2->SetAttribute("name","me");

element->LinkEndChild( element2 );
element2->LinkEndChild( text2 );
}

doc.SaveFile( "madeByHand2.xml" );
