TinyXML最新的发布版本是2.5.3,一直想用,今天拿出点时间用了用,现在把所掌握的初步简单用法整理一下。
首先编译库文件,TinyXML有两个编译版本,取决于是否使用STL。Build之后在新程序代码中include库中的tinyxml.h即可。下面是我的代码:
#
include <cstdio>
# include <iostream>
# include "../tinyxml.h"
# include <iostream>
# include "../tinyxml.h"
int main()
{
TiXmlDocument myDoc( "TestTinyXML.xml");
myDoc.InsertEndChild( TiXmlDeclaration( "1.0", "gb2312", "yes") );
myDoc.InsertEndChild( TiXmlElement( "RootNode") );
TiXmlElement* rootNode = myDoc.RootElement();
TiXmlElement* subElem = rootNode->InsertEndChild( TiXmlElement( "SubNode:Size") )->ToElement();
subElem->SetAttribute( "value", 16);
subElem->InsertEndChild( TiXmlText( "Text size") );
myDoc.InsertEndChild( TiXmlElement( "RootNode") );
TiXmlElement* rootNode = myDoc.RootElement();
TiXmlElement* subElem = rootNode->InsertEndChild( TiXmlElement( "SubNode:Size") )->ToElement();
subElem->SetAttribute( "value", 16);
subElem->InsertEndChild( TiXmlText( "Text size") );
myDoc.SaveFile();
myDoc.Clear();
myDoc.Clear();
myDoc.LoadFile( "TestTinyXML.xml");
TiXmlHandle docHandle( &myDoc);
TiXmlDeclaration* pDec = myDoc.FirstChild()->ToDeclaration();
if( pDec)
std::cout << "Version: " << pDec->Version() << "\nEncoding: " << pDec->Encoding() << "\nStandalong: " << pDec->Standalone() << "\n";
TiXmlHandle docHandle( &myDoc);
TiXmlDeclaration* pDec = myDoc.FirstChild()->ToDeclaration();
if( pDec)
std::cout << "Version: " << pDec->Version() << "\nEncoding: " << pDec->Encoding() << "\nStandalong: " << pDec->Standalone() << "\n";
subElem = docHandle.FirstChildElement().Element();
char* pch = ( char*)subElem->GetText();
if( !pch)
{
subElem = subElem->FirstChild()->ToElement();
if( subElem)
{
pch = ( char*)subElem->GetText();
if( pch)
std::cout << pch << " is ";
std::cout << subElem->Attribute( "value") << "\n";
} // if
} // if
char* pch = ( char*)subElem->GetText();
if( !pch)
{
subElem = subElem->FirstChild()->ToElement();
if( subElem)
{
pch = ( char*)subElem->GetText();
if( pch)
std::cout << pch << " is ";
std::cout << subElem->Attribute( "value") << "\n";
} // if
} // if
return 0;
}
}
程序运行输出如下:
Version: 1.0
Encoding: gb2312
Standalong: yes
Text size is 16
执行后会生成一个TestTinyXML.xml文件,其内容如下:
Encoding: gb2312
Standalong: yes
Text size is 16
执行后会生成一个TestTinyXML.xml文件,其内容如下:
<?xml
version
="
1.0"
encoding="gb2312"
standalone="yes"
?>
< RootNode >
<SubNode:Size value=" 16" >Text size </SubNode:Size>
</ RootNode>
< RootNode >
<SubNode:Size value=" 16" >Text size </SubNode:Size>
</ RootNode>
这个小玩意儿别看小,但可以说是短小精悍呢,足够我目前用了。今天先整理出这些,有时间再写。
